Question

Why is it important to rename 4 1/4 if you subtract 3/4 from it

Answer 1

Causes it makes it easier it would turn into 17/4-3/4 which equals 14/4 which equals 7/2 which equals 3 1/2

Answer 2

Because it makes it easier if you reduce it to 17/4 and then you can subtract 3/4 witch would be 14/4
