If x be the required number,we may write it in ratio form
x/12=100/15
=>15x=1200 (by cross multiplication)
=>x=1200/15=80 ans.

15/100 * x = 12
x = 12 / (15/100)
x = 12 * (100/15)
x = 1200/15
x = 80

12 = .15x
x = 12/.15 = 120/1.5 = 80

Reanslate the sentence from English to Math on word at a time:
English Math
12 12
is =
15% .15
of * (multiply)
what number n
Then rewrite it as a math sentence:
12 = .15 * n
Now solve:
divide both sides by .15
n=80
