Answer 1

Answer:

Well the answer isn't EXACTLY 3 feet, but it's very close at 2.91

Step-by-step explanation:

First we convert all values to decimals to save time.

To convert a mixed number to a decimal you divide the numerator by the denominator and put the whole number in front of it

7/8=0.875

0.875+7=7.875

5/8=0.625

0.625+3=3.625

1/4=0.25

0.25+1=1.25

Now we subtract the original value (7 7/8 or 7.875) from all the cut pieces to find out how much is left.

7.875-3.625=4.16

4.16-1.25=2.91.

And there you go.
