Question

A ​60-inch cardboard is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece.

Answer 1

A 60-inch board is cut into two pieces

x + y = 60

one piece is four times as long as the other

x = 4y

4y + y = 60

5y = 60

y = 12

x = 48

Answer 2

It’s basically long piece to small piece so 4:1, you add both numbers which gives you 5 and divide 60 by 5. That gives you a total of 12 then all you have to do is times that by the number previously given so longer piece would be 4 times 12 is 48 and shorter piece would be 1 times 12 so 12
