find the base when the amount and percent are known

amount / percent = base

convert 18 % to decimal

remove the % symbol. divide 18 by 100

18 / 100 = 0.18

divide 27 by the decimal

27 / 0.18 = 150

The base is 150

27 is 18% 0f 150

Remember that you can write 18% as a decimal. To write a percentage as a decimal merely move the decimal point to the left two spaces. For example 18.0% = .18 - the decimal point has moved to the left two spaces.

The word "of" is represented mathematically as multiplication, so in your question "18% of ?" means "18% times ?". When typing it is convenient to use "*" to represent multiplication, so "18% * ?"

Finally the "?" in your question is the unknown, it is what we are trying to find, so we can represent it with a variable. To stick with convention we will use "x" fpr "?".

Putting all this knowledge together we can re-write the equation:

27 = 18% of ?
27 = 0.18 *x

Now we want to get 'x' by itself. To do this we must look at what operation is occurring to "x" and do the opposite to both sides of the equation. "x" is being multiplied by 0.18, and the opposite of multiplication is division so:

27/0.18 = (0.18*x)/0.18 -> notice on the right the two .18s will cancel out:

150= x

And there you have it: 27 is 18% of 150 . I hope this helps, good luck on other problems like this.

Write it like this:
27 = 18% (X)
or:
27 = (18/100)(X)
Multiply both sides by 100/18:
27(100/18) = X
150 = X

I will not give you the answer but cross multiply 27=18
x 100

Let 27 = 18% of x

So 27 = 0.18 * x
So x = 27/0.18
= 3/0.02
= 150

So 27 = 18% of 150

1-18%*5.55555556=100%
27*5.55555556=150
2-100%:18%=5.55555556
x : 27=5.55555556==>x=27*5.55555556=150
