**Sharing Equally**

Use drawings to help you solve the problems. Solve each problem in more than one way. Show your work.

Question 1.

Four friends shared 5 pizzas equally. How much pizza did each friend get?

____ pizzas

One way:

Another way:

Answer:

Explanation :

First Way :

Number of Pizzas = 5

Number of people = 4

Each Person take a pizza, number of pizzas taken = 4 pizzas

Number of pizzas left = 1

Fraction of pizza each person get = \(\frac{1}{4}\).

Fraction of pizza each person get = 1 + \(\frac{1}{4}\) = \(\frac{5}{4}\) .

Second Way :

Number of Pizzas = 5

Number of people = 4

Each pizza is divided into 4 parts .

Each person takes 1 pizza slice .

Fraction of each pizza slice = \(\frac{1}{4}\)

Total Fraction of 5 pizza slices = 5 × \(\frac{1}{4}\) = \(\frac{5}{4}\)

Therefore , Each person gets \(\frac{5}{4}\) fraction of pizza that means each person gets 1 slice from 5 pizzas .

it is represented in above figure with different colors .

Question 2.

Five kittens are sharing 6 cups of milk equally. How much milk does each kitten get?

____ cups of milk

One way:

Another way:

Answer:

One Way :

Number of Kittens = 5

Number of cups of milk = 6

Each kittens gets 1 cup that means 5 cups of milk is given to 5 kittens .

1 cup of milk is left which is shared by 5 kittens .

Fraction of milk given to each kitten in 1 cup = number of cups ÷ number of kittens = 1 ÷ 5 =

Total cups of milk given each kitten = 1 + \(\frac{1}{5}\) = \(\frac{5}{5}\) + \(\frac{1}{5}\) = \(\frac{6}{5}\) cups .

Another Way :

Number of Kittens = 5

Number of cups of milk = 6

Each cup of milk is divided into 5 parts .

Each kitten is given \(\frac{1}{5}\) cup of milk

As there are 6 cups Each kitten gets 6 × \(\frac{1}{5}\) cup of milk = \(\frac{6}{5}\) cups of milk .

Therefore each kitten gets \(\frac{6}{5}\) cups of milk .

### Everyday Math Grade 4 Home Link 3.4 Answer Key

**Finding Equivalent Fractions**

Family Note Today students learned about an Equivalent Fractions Rule, which can be used to rename any fraction as an equivalent fraction. The rule for multiplication states that if the numerator and denominator are multiplied by the same nonzero number, the result is a fraction that is equivalent to the original fraction.

For example, the fraction \(\frac{1}{2}\) can be renamed as an infinite number of equivalent fractions.

When you multiply the numerator 1 by 5, the result is 5. When you multiply the denominator 2 by 5, the result is 10.

\(\frac{1 \times 5}{2 \times 5}\) = \(\frac{5}{10}\)

This results in the number sentence \(\frac{1}{2}\) = \(\frac{5}{10}\). If you multiplied both the numerator and denominator in \(\frac{1}{2}\) by 3, the result would be \(\frac{3}{6}\), which is also equal to \(\frac{1}{2}\).

Fill in the boxes to complete the equivalent fractions.

Example:

Question 1.

Answer:

\(\frac{1}{2}\) = \(\frac{6}{12}\)

Explanation :

The fraction \(\frac{1}{2}\) can be renamed as an infinite number of equivalent fractions.

When you multiply the numerator 1 by 6, the result is 6. When you multiply the denominator 2 by 6, the result is 12.

\(\frac{1 \times 6}{2 \times 6}\) = \(\frac{6}{12}\)

This results in the number sentence \(\frac{1}{2}\) = \(\frac{6}{12}\).

Question 2.

Answer:

\(\frac{1}{4}\) = \(\frac{3}{12}\)

Explanation :

The fraction \(\frac{1}{4}\) can be renamed as an infinite number of equivalent fractions.

When you multiply the numerator 1 by 3, the result is 3. When you multiply the denominator 4 by 3, the result is 12.

\(\frac{1 \times 3}{4 \times 3}\) = \(\frac{3}{12}\)

This results in the number sentence \(\frac{1}{4}\) = \(\frac{3}{12}\).

Question 3.

Answer:

\(\frac{1}{3}\) = \(\frac{2}{6}\)

Explanation :

The fraction \(\frac{1}{3}\) can be renamed as an infinite number of equivalent fractions.

When you multiply the numerator 1 by 2, the result is 2. When you multiply the denominator 3 by 2, the result is 6.

\(\frac{1 \times 2}{3 \times 2}\) = \(\frac{2}{6}\)

This results in the number sentence \(\frac{1}{3}\) = \(\frac{2}{6}\).

Question 4.

Answer:

\(\frac{2}{3}\) = \(\frac{8}{12}\)

Explanation :

The fraction \(\frac{2}{3}\) can be renamed as an infinite number of equivalent fractions.

When you multiply the numerator 2 by 4, the result is 8. When you multiply the denominator 3 by 4, the result is 12.

\(\frac{2 \times 4}{3 \times 4}\) = \(\frac{8}{12}\)

This results in the number sentence \(\frac{2}{3}\) = \(\frac{8}{12}\).

This results in the number sentence \(\frac{1}{5}\) = \(\frac{2}{10}\).

Question 6.

Answer:

\(\frac{2}{5}\) = \(\frac{4}{10}\)

Explanation :

The fraction \(\frac{2}{5}\) can be renamed as an infinite number of equivalent fractions.

When you multiply the numerator 2 by 2, the result is 4. When you multiply the denominator 5 by 2, the result is 10.

**Solving Fraction Comparison Number Stories**

Solve the problems below.

Question 1.

Tenisha and Christa were each reading the same book. Tenisha said she was \(\frac{3}{4}\) of the way done with it, and Christa said she was \(\frac{6}{8}\) of the way finished. Who has read more, or have they read the same amount? Ho w do you know?

Answer:

Fraction of book read by Tenisha = \(\frac{3}{4}\)

Fraction of book read by christa = \(\frac{6}{8}\) = \(\frac{3}{4}\) .

\(\frac{3}{4}\) = \(\frac{6}{8}\)

Explanation :

The fraction \(\frac{6}{9}\) can be renamed as an infinite number of equivalent fractions.

When you divide the numerator 6 by 2, the result is 3. When you divide the denominator 8 by 2, the result is 4.

\(\frac{6 ÷ 2 }{8 ÷ 2 }\)= \(\frac{3}{4}\)

This results in the number sentence \(\frac{3}{4}\) = \(\frac{6}{8}\).

Question 2.

Heather and Jerry each bought an ice cream bar. Although the bars were the same size, they were different flavors. Heather ate \(\frac{5}{8}\) of her ice cream bar, and Jerry ate \(\frac{5}{10}\) of his.

Who ate more, or did they eat the same amount? ___

Write a number sentence to show this. ___

Answer :

Explanation :

Fraction of ice cream ate by Heather = \(\frac{5}{8}\)

Fraction of ice cream ate by Jerry = \(\frac{5}{10}\)

Both the ice creams bar are represented in the above figure .

from the above figure we notice that \(\frac{5}{8}\) > \(\frac{5}{10}\) that means Jerry ate more ice cream bar than Heather .

Question 3.

Howard’s baseball team won \(\frac{7}{10}\) of its games. Jermaine’s team won \(\frac{2}{5}\) of its games. They both played the same number of games.

Whose team won more games, or did they win the same amount? ___

How do you know? __________

Answer:

Fraction of games won by Howard’s = \(\frac{7}{10}\)

Fraction of games won by Jermaine’s = \(\frac{2}{5}\)

\(\frac{7}{10}\) >\(\frac{2}{5}\) that means Howard won more games than Jermaine as it shown in the above figure .

Question 4.

Write your own fraction number story. Ask someone at home to solve it.

Answer:

Cristine had 4/5 m of cloth. She used 3/4 of it to make handkerchiefs. How much cloth had she left?

Explanation :

Fraction of total cloth with Cristine = \(\frac{4}{5}\) m

Fraction of cloth used = \(\frac{3}{4}\) m

Fraction of cloth left = \(\frac{4}{5}\) – \(\frac{3}{4}\) m = \(\frac{16}{20}\) – \(\frac{15}{20}\) = \(\frac{1}{20}\) m .

Therefore, Fraction of cloth left = \(\frac{1}{20}\) m .

**Comparing and Ordering Fractions**

Write the fractions from smallest to largest, and then justify your conclusions by placing the numbers in the correct places on the number lines.

Question 1.

Answer:

Explanation :

1. A fraction is larger if it’s farther from 0 on the number line.

2. A fraction is smaller if it’s closer to 0 on the number line.

\(\frac{5}{6}\) is farther from 0 so, it is greater number .

\(\frac{2}{6}\) is closer to 0 so, it is smaller number .

Therefore, \(\frac{2}{6}\) < \(\frac{4}{6}\) < \(\frac{5}{6}\) .

Question 2.

Answer:

Explanation :

1. A fraction is larger if it’s farther from 0 on the number line.

2. A fraction is smaller if it’s closer to 0 on the number line.

\(\frac{9}{10}\) is farther from 0 so, it is greater number .

\(\frac{1}{4}\) is closer to 0 so, it is smaller number .

Therefore, \(\frac{1}{4}\) < \(\frac{5}{12}\) < \(\frac{3}{5}\) < \(\frac{9}{10}\) .

Question 3.

Answer:

Explanation :

1. A fraction is larger if it’s farther from 0 on the number line.

2. A fraction is smaller if it’s closer to 0 on the number line.

\(\frac{2}{3}\) is farther from 0 so, it is greater number .

\(\frac{1}{6}\) is closer to 0 so, it is smaller number .

Therefore, \(\frac{1}{6}\) < \(\frac{4}{10}\) < \(\frac{1}{2}\) < \(\frac{7}{12}\) < \(\frac{2}{3}\) .
