## McGraw-Hill My Math Grade 3 Answer Key Chapter 10 Lesson 7 Fractions as One Whole

Whole numbers can be written as fractions. When the numerator is the same as the denominator, the fraction equals 1.

**Math in My World**

**Example 1**

There are 4 panes of glass in one window of Landon’s classroom. Each pane of glass is \(\frac{1}{4}\) of the whole window.

How many fourths equal 1 whole?

Place a point on the number line to graph this fraction. The models show that and 1 share the same point and have the same size.

So, 4 fourths = ________________ whole. Or, = 1.

Answer:

Given that,

There are 4 panes of glass in one window.

Each pane of glass is \(\frac{1}{4}\) of the whole window.

So, 4 fourths equal to 1 whole or 4/4 = 1.

**Example 2**

How many wholes are in \(\frac{3}{1}\)?

Think:

So, = \(\frac{3}{1}\) or ___________. There are ____________ wholes in \(\frac{3}{1}\).

Answer:

Given that,

\(\frac{3}{1}\) or 3/1.

There are 1 whole in the \(\frac{3}{1}\).

**Talk Math**

How can you tell whether \(\frac{6}{1}\) is greater or less than 1?

Answer:

Given that,

The latex is \(\frac{6}{1}\) = 6/1.

6/1 = 6.

6 is greater than 1.

Therefore \(\frac{6}{1}\) is greater than 1.

**Guided Practice**

**Write a fraction to represent the shaded part of each whole or set of wholes.**

Question 1.

Answer:

The fraction to represent the shaded part of each whole is = shaded part/ number of parts

= 8/8 = 1.

Therefore the fraction of the shaded part is 8/8.

Question 2.

Answer:

The fraction to represent the shaded part of each set of wholes is = shaded part/ number of parts

= 4/1

Therefore the fraction of the shaded part is 4/1.

**Independent Practice**

**Write a fraction to represent the shaded part of each whole or set of wholes.**

Question 3.

Answer:

The fraction to represent the shaded part of each whole is = shaded part/ number of parts

= 4/4 = 1.

Therefore the fraction of the shaded part is 4/4.

Question 4.

Answer:

The fraction to represent the shaded part of each set of whole is = shaded part/ number of parts

= 2/1

Therefore the fraction of the shaded part is 2/1

Question 5.

Answer:

The fraction to represent the shaded part of each whole is = shaded part/ number of parts

= 2/2 = 1.

Therefore the fraction of the shaded part is 2/2.

Question 6.

Answer:

The fraction to represent the shaded part of each set of whole is = shaded part/ number of parts

= 6/1

Therefore the fraction of the shaded part is 6/1.

Question 7.

Answer:

The fraction to represent the shaded part of each whole is = shaded part/ number of parts

= 8/8 = 1

Therefore the fraction of the shaded part is 8/8.

Question 8.

Answer:

The fraction to represent the shaded part of each set of whole is = shaded part/ number of parts

= 8/1.

Therefore the fraction of the shaded part is 8/1.
