Question

Help! I need work too. I have a test tomorrow and I don't know how to solve this.

20% of what number is 7?

Answer 1

20        7
----- = ------
100      x

100 x 7 = 700
700/20 = 35
X = 35

Answer 2

The answer is 35% put 7/20= n/100 do cross multiplication, 7×100= 700 then do 700/20= 35%
