Question

Sean has a piece of string 7/8 meter long. He uses 1/5 of the piece of string to tie a package and cuts the rest into 5 equal pieces. What is the length of each piece?

Answer 1

Let change 7/8 and 1/5 into decimal point so 0.88 and 0.2 
0.88-0.2 =0.68
then we want 5 equal length so we divided
0.68 / 5 =0.14
