Question

Explain why you must rename 2 7/12 in order to find 2 7/12-5/6


Help plsssssss

Answer 1

Denominators must be the same

Answer 2

Answer

its hard but here we go

Step-by-step explanation

Since the lowest common denominator between 12 an 6 is 12 you don't change it yet. You have to change 5/6 to 10/12. 10/12 is greater than 7/12 so you have to change the fraction to 1 19/12. When you have to subtract you can do the rest.
