7/9 - 1/12 in the lowest terms

What is the least common denominator between these two fractions?

OpenStudy (anonymous):

36 i believe ?

OpenStudy (anonymous):

Yup so when you subtract fractions they have to have the same denominator. When you multiply 9x4 to get 36 you need to do the same for the 7. 12x3=36 so you need to multiply 1x3 on the top for the second fraction. Got this?

OpenStudy (anonymous):

OpenStudy (anonymous):
