July.

How much rain did the city receive in July?

Answer 1

r = 10/7 inch

the total amount of rain the city received in July is 10/7 inch.

Explanation:

Let r represent the total amount of rain the city received in July.

The equation 4/10r = 4/7

Can be used to find the amount of rain r in inches the city received in July.

Solving the equation;

4/10 r = 4/7

Multiply through by 10/4;

4/10 r × 10/4 = 4/7 × 10/4 = 10/7

r = 10/7 inch

the total amount of rain the city received in July is 10/7 inch.
