Question

Explain why it is necessary to rename 4 and 1/4 if you subtract three fourths from it.

Answer 1

Rename four and one fourth when subtracted from three fourths because when you subtract the fractions you get a different fraction for your answer.

4 1/4 - 3/4 = 3 1/2

so it's three and one half instead of four and one fourths!
