w+7/8=5 first remove the fraction from the equation

Question

you are supposed to remove the fraction from the equation by multiplying something but i don't understand how to do that

Answer 1

Multiply both sides of the equation by , $8$. This clears the fractions.

8(w+7/8)=8(5)

8w+7=40

8w=40-7

8w=33

w=33/8
