## HMH Into Math Grade 6 Module 7 Answer Key Understand and Apply Percent

A nature club held a beach cleanup. Four club members described the length of the beach that they each cleaned.

Find the total amount of beach the club cleaned.

A. Write a fraction with a denominator of 10 or 100 that is equal to each decimal.

0.16 = ____ 0.28 = ____

0.3 = ____ 0.2 = ____

Answer:

0.16 = \(\frac{16}{100}\), 0.28 =\(\frac{28}{100}\),

0.3 = \(\frac{3}{10}\), 0.2 = \(\frac{2}{10}\),

Explanation:

Wrote a fraction with a denominator of 10 or 100 that is equal to each decimal as

0.16 = \(\frac{16}{100}\), 0.28 =\(\frac{28}{100}\), 0.3 = \(\frac{3}{10}\),

0.2 = \(\frac{2}{10}\).

B. What length of the beach did the club clean?

0.94 mile,

Explanation:

Given a nature club held a beach cleanup.

Four club members described the length of the beach that they each cleaned the total amount of beach the club cleaned are Kurt – 0.16 mile, Maria – 0.3 mile,

Eddie – 0.28 mile and Celia – 0.2 mile so total is 0.16 mile + 0.3 mile + 0.28 mile + 0.2 mile = 0.94 mile.

**Turn and Talk**

- How does the length of beach cleaned with 1 mile? How do you know?
- How would the length of beach cleaned change if Kurt cleaned \(\frac{6}{100}\) mile more ? Justify your response.

Are You Ready?

Answer:

If all the four and Kurt one more time, If Kurt cleaned \(\frac{6}{100}\) mile then

the length of beach cleaned changes to 0.84 mile,

Explanation:

The length of beach cleaned with 1 mile as all the four plus again Kurt one more time

as 0.94 mile + 0.16 mile = 1.1 mile, If Kurt cleaned \(\frac{6}{100}\) mile then

the length of beach cleaned changes to 0.06 mile + 0.3 mile + 0.28 mile + 0.2 mile = 0.84 mile.
