frank gets a pay rise from £120 a week to £135 a week. what fraction of his original pay was his pay rise?

Question

please help my teacher didn’t teach me this and it’s in a test :(

Answer 1

So what was your raise?
135-120
= $15

Original pay = 120

"what fraction of his original pay was his pay rise??

can you not form the fraction 15/120 and reduce it to 1/8 ????
