Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.

no, to add and subtract like and unlike fractions the denominator has to be the same,

No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.

he fact that they are improper is irrelevant. Re-scale the fractions so that they have the same denominator and thenadd or subtract as required.

it stay the same when you subtract fractions and when you add fractions.

The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.

In order to add or subtract fractions, they must have the same denominator.

You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.

Subtract as if there were no denominators.

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.

Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.

if they have the same denominator just subtract it . if it doesn't than find the denominator.
