Q.10   0.25(4f – 3) = 0.05(10f – 9)

Answers (1)

We have 

                  0.25(4f – 3) = 0.05(10f – 9)

Let us open the brackets:

                f - 0.75 = 0.5f - 0.45

or             f - 0.5f = - 0.45 + 0.75

or                 0.5f  =  0.30  

 Dividing both sides by 0.5, we get 

                      f = 0.6
