Thread: [SOLVED] Percent of a Number

When I have a question like:

5 is 12% of what number. How do I do it?

The way I learned it is you say

5 is to 12% as x is to 100%

or

5/12 =x/100

or

(5/12)*12=(x/100)*12

or

5=12x/100

or

5*100=(12x/100)*100

or

500=12x

or x= 500/12

or x = 125/3

Translation:
"is" = "="
"of" = "*"
"%" = "*0.01"

Relation:
5 = 12*0.01 * x

Answer:
x = 125/3 (approximately 41.667)
