Question

If 60 marks is 40%, how much is full marks (Show your working out)?

Answer 1

' 40% ' means 0.4 .

You said that                           60          = 0.4 x Full

Divide each side by 0.4 :       60 / 0.4  =   1  x Full

                                                       Full  =  150 .

Answer 2

60/X = 40/100
60•100=40X
6000=40X
6000/40=X
150=X

60 is 40% of 150
