Find the base when the amount and percent are known

amount / percent = base

First convert 25 % to decimal

remove the % symbol. divide 25 by 100

25 / 100 = 0.25

divide 18 by the decimal

18 / 0.25 = 72

The base is 72

18 is 25% of 72

Find the percent when the amount and base are known

let

18 = amount

60 = base

amount / base = percent

18 / 60 = 0.3

Multily the decimal by 100 and attact the % symbol

0.3 x 100 = 30

The percent is 30%

First question:
Let n be "the number"
Then: 18 = 25% x n
Divide both sides by 25% or 0.25:
72 = n

Second question:
Let p be "the percent"
Then: 18 = p x 60
Divide both sides by 60:
0.3 = p or
30% = p

Well, to make it short and sweet...

there is 100% in a number and that number is X correct, now you have 25% which is 1/4 Do you get it so far? Ok now in order to get the full 100% your going to have to add 3 more quarters and each quarter is equal to 18 correct? Ok, being that said your answer should be 72

well take care

18 = 25x/100
1800 = 25x
x = 1800/25 = 18 *4 = 72
ANS: 18 is 25% of 72


18/60 = x/100
1800 = 60x
x = 30
ANS: 18 is 30% of 60
