## 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 = ____
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.

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.
