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

To understand why it is necessary to rename 4 1/4 if you subtract 3 1/4, we need to understand the concept of renaming fractions and why it is important.
When subtracting fractions, we need to have a common denominator. The denominator represents the number of equal parts into which a whole is divided, and the numerator represents the number of those parts we're dealing with. In this case, both 4 1/4 and 3 1/4 have a denominator of 4.
To subtract the fractions, we subtract the numerators while keeping the denominator the same. So, subtracting 3 1/4 from 4 1/4 would result in:
4 1/4 - 3 1/4 = (4 - 3) 1/4 = 1 1/4
However, in order to represent the result as a mixed number (a whole number and a fraction), we need to make sure the numerator is smaller than the denominator. In this case, the numerator 1 is already smaller than the denominator 4, so we don't need to rename or simplify the fraction.
Therefore, it is not necessary to rename 4 1/4 when subtracting 3 1/4 in this specific case. However, there may be instances where renaming is required when performing other operations or working with different fractions. It's important to understand when and how to rename fractions in order to perform accurate calculations.
