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?

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