EXPLAIN WHY IT IS NECESSARY TO RENAME 4 1FORTH IF YOU SUBTRACT 3 FOURTH

It's easier to subtract or add similar fractions, rather than fractions and whole numbers.
4 1/4  3/4 = ???
5/4  4/3  2/4 = 1/2

1/4 is lesser than 3/4 ,so 3/4 can not subtract from 1/4 .
4 1/4 gets renamed to 3 5/4
then 4 1/4  3/4 =3 5/4  3/4
=3 2/4
