Question

If a 25 ft rope is cut into two sections with one section 4 times as long as the other section, how long is the shorter piece?

Answer 1

We are given the ratio
Long : short = 4:1
and the sum
Long+short=25
=>
long = 25*(long/(long+short)=25*(4/(4+1))=20
Short =25*(short/(long+short)=25*(1/4+1)=5
