What is 15/12 in simplest form?

Okay so you would divide both by 3 getting 5/4

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
