Question 1.
A cook measures the mass of salt and puts it in a bowl. Then she measures the mass of pepper and puts it in the same bowl. What is the mass of the salt and pepper mixture?
$HMH Into Math Grade 4 Module 14 Lesson 6 Answer Key Add Fractional Parts of 10 and 100 1$
You can add two fractions if they have the same denominator. When fractions have the same denominator, they have a common denominator. The fractions $\frac{4}{10}$ and $\frac{25}{100}$ do not have a common denominator.

Connect to Vocabulary
A common denominator is a denominator that two or more fractions share.
Example: $\frac{5}{8}$, $\frac{2}{8}$

A. You can always rename a fraction with a denominator of 10 as an equivalent fraction with a denominator of 100.
$HMH Into Math Grade 4 Module 14 Lesson 6 Answer Key Add Fractional Parts of 10 and 100 2$
Answer:

B. Now you can add the fractions.
$HMH Into Math Grade 4 Module 14 Lesson 6 Answer Key Add Fractional Parts of 10 and 100 3$
Answer:

C. What is the mass of the salt and pepper mixture?
Answer:
$\frac{65}{100}$
Explanation:
Mass of salt $\frac{4}{10}$ and mass of pepper $\frac{25}{100}$
Make the fraction of mass as equivalent fractions by multiplying the numerator and denominator with 10.

Then add the both the masses to find the sum.

Question 2.
A wallaby jumps $\frac{7}{10}$ meter. Then it jumps $\frac{18}{100}$ meter. How far does the wallaby jump after jumping twice?
$HMH Into Math Grade 4 Module 14 Lesson 6 Answer Key Add Fractional Parts of 10 and 100 4$
A. Write an equation to model the problem. Use j for the distance the wallaby jumps after jumping twice.
Answer:
j = $\frac{7}{10}$ + $\frac{18}{100}$

B. Rename $\frac{7}{10}$ as a fraction with a denominator of 100.
$\frac{7}{10}$ = ____________
Answer:

C. Find the value of j.
Answer:

D. How far does the wallaby jump after jumping twice?
Answer:
$\frac{88}{100}$
Explanation:
A wallaby jumps $\frac{7}{10}$ meter.
Then it jumps $\frac{18}{100}$ meter.
Total jump after jumping twice = $\frac{88}{100}$ meter.

Turn and Talk Why can you always rename a tenth as a hundredth?
Answer:
When the fractions have the denominators as tenth and hundredth than multiply the number of tenths by 10 to convert to hundredths,
to equalize the denominators of both the fractions.

Question 6.
Attend to Precision Daniel collects rocks. What is the total mass of the piece of quartz and the piece of obsidian?
$HMH Into Math Grade 4 Module 14 Lesson 6 Answer Key Add Fractional Parts of 10 and 100 5$
You can use the hundredths model to help you rename $\frac{5}{10}$ as a fraction with a denominator of 100.
Model the problem with an equation. Let m = the total mass of the two rocks. Then find the value of m.
Answer:
m = $\frac{77}{100}$
Explanation:
mass of quartz = $\frac{27}{100}$
mass of obsidian = $\frac{5}{10}$
m = total mass of the two rocks

Question 13.
Reason Olivia needs to empty three of the beakers below into a jar that holds $\frac{3}{4}$ liter. Circle the three beakers that Olivia should empty into the jar.
$HMH Into Math Grade 4 Module 14 Lesson 6 Answer Key Add Fractional Parts of 10 and 100 8$
Explain how you chose the right beakers.
Answer:

Explanation:
Olivia needs to empty three of the beakers, if he empty the jars of $\frac{15}{100}$ liter, $\frac{4}{10}$ liter and $\frac{11}{100}$ liter it equal to $\frac{3}{4}$ liter.
$\frac{3}{4}$ liter x $\frac{25}{25}$ liter = $\frac{75}{100}$ liter
