To solve this you must use a proportion like so...
[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]
60 is a percent and percents are always taken out of the 100. This means that one proportion will have 60 as the part and 100 as the whole
We want to know out of what number is 12 60%. This means 12 is the part and the unknown (let's make this x) is the whole
[tex]\frac{12}{x} =\frac{60}{100}[/tex]
Now you must cross multiply
12*100 = 60*x
1200 = 60x
To isolate x divide 60 to both sides
1200/60 = 60x/60
20 = x
This means that 60% of 20 is 12
Hope this helped!
