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.

- 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.
