Question

A length of tape is 135 centimetres long. It is cut into two pieces. The first piece is twice

as long as the second piece. How long is the shorter of the two pieces of tape?

Answer 1

45

Explanation:

let the longer tape be x

shorter tape be y

given

x+y=135⇒equation 1

also given

2y=x⇒equation 2

subtituting eq2 in eq1

2y+y=135

3y=135

y=135/3=45

hope this helps
