two years ago the water in a local reservoir fell 8 3/4 feet then it rose 4 3/5 how much did it change

2 answers:

8 0

To find the change, we need to subtract.

8 3/4 - 4 3/5

We need a common denominator to find the answer.

3*5/4*5 = 15/20

8 15/20

3*4/5*4 = 12/20

4 12/20

Now we can properly subtract

8-4=4

15-12
-------- =
20

3/20

Now we have our final answer: 4 3/20

The change : 4 3/20
