Question

peggy practices her gymnastics routine for a total of 21 hours . each practice session is 1 3/4 hours . how many practice sessions does Peggy have.

Answer 1

Peggy has 12 practice sessions

The first step is finding the unit rate. We can do this by evaluating

21/1.75 divided by 1.75/1.75.
When you divide the two, you get 12.

To check your work you do 12(1.75) and you will get 21

Answer 2

Answer:

12

Step-by-step explanation:

To find the answer, you divide 21 by 1 3/4.

21→21/1

1 3/4→7/4

You then find the reciprocal of the divisor.

7/4→4/7

Multiply.

21/1 ×4/7=84/7→12

The answer is 12.
