The number 6 is 30% of what?
balu736 [363]
<span>So we wan't to know from which number can we take 30% and get 6. Well, lets turn that into an equation. Lets say that x is the number we are looking for. So, 30% of x is equal 6 or mathematically: 30% * x = 6. Now: (30/100)*x=6 and when we multiply both sides with 100 and divide both sides with 30 we get: x=(6*100)/30 and that is equal to: x=20. So 30% out of 20 is 6. </span>

7x3=21
