Engage NY Math Grade 4 Module 6 Lesson 7 Problem Set Answer Key 1

Answer:
a.20.53.

Explanation:
In the above-given question,
given that,
2 tens + 5 tenths + 3 hundredths.
2 tens = 20.
5 tenths = 5/10.
5/10 = 0.5.
3 hundredths = 3/100.
3/100 = 0.03.
20 + 0.5 + 0.03 = 20.53.

Answer:
b.20.53.

Explanation:
In the above-given question,
given that,
5 hundred + 4 hundredths.
5 hundred = 500.
4 hundredths = 4/100.
4/100 = 0.04.
500 + 0.04 = 500.04.
