15/12 in simplest form.
If you want it in improper fraction form, simply divide both the denominator (bottom number) by 3, and divide the numerator (top number) by 3 as well :)
15 ÷ 3 = 5
12 ÷ 3 = 4
So, your answer, in improper fraction form, is 5/3
However, if you want it in mixed form, you have to turn 15/12 into a mixed number.
1 3/15
Simplify by dividing both the numerator and denominator by 3.
3 ÷ 3 = 1
15 ÷ 3 = 5
So, your answer, in mixed number form, is 1 1/5
