Answer 1

These questions were always trick to me in school, but one teacher always explained it to me very well...

Wherever it says "is" that is an equal sign.
Wherever it says "of" that is an multiplication sign.
And just assign your variable "x" to the "what number or what percentage" part.

Convert any percnetages into a decimal form.

24.) 45% of what distance is 135 miles?

this would become the equation .45x=135
then solve for x

55 years is what percent of 20 years?
this would become the equation 55=x20 or 20x=55

Once you get the equations, the rest is algebra... solving for x.

When you're looking for a percentage, don't forget to multiply x by 100 to get the right answer.

So if you get .40 for a percentage answer.... it's really 40%

I'm not gonna do all your homework for ya, but I hope my explanation helps.
