What percent of 49 is 7

Question

Need help on percents propirtion and how to set up the ratio ir fraction to cross multiply Please.

Answer 1

"Percent" means "of one hundred," which is why one penny is "one cent"

Just a little trivia to help you understand the set-up.

 

 7       X

--- = -----

49     100

 

Or, if it's not lined up right, 7/49 is equal to X/100

 

We're solving for X, so we need to cross-multiply our numbers:

7 * 100 = 49x, leading to 700 = 49x

 

Now to get X by itself, we now have to divide both sides by 49:

700 / 49 = (49x)/49

700 / 49 = 14.2857 = x

 

So it looks like 14.2857/100, which gives us 14.28% when properly rounded.
