how do you find percents?

Question

the question is 18 is 25% of what number

Answer 1

"18" --> 18
"is" --> =
"25 percent" --> 25/100
"of" --> *
"what number" --> n

18 = ( 25/100 ) * n
18 = 1/4 * n
18 * 4 = n
72 = n

18 is 25% of 72

Answer 2

Percent is calculated as the result of dividing the factional portion by the whole amount then multipling that value by 100. For example if you have 10 pieces out of 75 then you would divide 6 by 75 giving 0.08. Multiply .08 by 100 and you get 8%. The math formula looks like this:
(fx / x) * 100 = y%

where x is the whole value
and fx is the fractional part of x
and y is the resulting percentage

Therefore you can take any percentage problem and apply it to this math formula and find the missing number. In your question, 18 takes the place of fx, 25 is y and you are looking for x

(18 / x) * 100 = 25%
18 / x = 0.25
x = 18 / 0.25
x = 72

Hope this helps!

Answer 3

Well, to find this, you first think: "What's 18*4?"

This is so because 25 percent is one-fourth of a whole, so that's four.

So, 18*4=72.

So, 18 is 25% of 72.

Answer 4

18 X 4 =72

Answer 5

the formula is:

18= 25/100 x

18 = 1/4 x - now multiply 4 to the each side-

72 = x

there is your answer! i hope i answered ur question the way u wanted

Answer 6

Saying "multiply it by 4" helps with the example, but it doesn't tell you how to solve other problems. Set it up like this

.25x = 18

x = 18/.25

x = 72

(25% = 25/100 = .25)

Answer 7

x * .25 = 18
x = 18/.25
72

or 25% is one quarter, 1 of 4. so 4 * 18 = 72

Answer 8

72

Answer 9

Well if 18 is 25%, wouldn't it be logical to just multiply it by 4 since there are 4 quarters in 100%?

Answer 10

18*4=72
so the ans. is 72
