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.

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.

Yes, but the numerator is different,same as adding fractions

First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators

Convert them to improper fractions with a common denominator.

If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.

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

If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.

You need a common denominator in order to add or subtract fractions.

Just subtract the numerators and copy the denominator
