A piece of metal 3 7/8 inches long is to be cute from a longer piece of 5 1/16 inches.What will be the length of the remaining piece?

Answer 1

make sure all the parts with fractions have the same denominator, then it should be easy.

7/8 = 14/16
So: 5 and 1/16 - 3 and 14/16

Answer 2

First, you need the common denominator -- so 3 7/8 = 3 14/16

5 1/16 - 3 14/16

Change: 5 1/16 to 4 17/16

4 17/16 - 3 14/16 = ?

Answer 3

So 1 3/16?But how did you change th 5 1/16 to 4 17/16?
