Question

What's the least common denominator of 7/12 1/3 and 3/4?​

Answer 1

12

Explanation:

3/4 can be written as 9/12, I did this by multiplying both the denominator and numerator by 3.

1/3 can be written as 4/12, I did this by multiplying both the denominator and numerator by 4.

And we don't need to change 7/12 because that is already in the denominator of 12.
