BlakeThis question can be written as 30=75% times X
75% can be simplified to either 3/4 or .75
The fraction makes more sense in my head, because I can easily see that 30 is three-fourths of a certain number. If this makes sense to you, don't bother reading the rest.
For the sake of the math sentence, though, I'll do it the decimal way.
So we re-write it as 30=.75*X
then we move the numbers onto one side of the equation and leave the X on the other, by dividing both sides by .75
So we're left with 30/.75 = X
with a calculator, we find that 30 divided by .75 is 40.
So X = 40
