The depth of a river in June was 4 feet. Later in the summer the depth of the river at the same spot was 3.2 feet. What was the percent of change in the depth of the river?

20 percent change in the depth of the river

Step-by-step explanation:

4 - 3.2 = .8

.8 x 100 = 80

80/4 = 20

20%

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
