Top Answer

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.

first u find a common denominator

What is the definition of Adding and Subtracting Like Fractions

It means you have to subtract fractions.

subtracting fractions

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.

Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.

yes you should use a common denominator when subtracting with fractions, it makes it much easier.

Subtracting a fraction is the same as adding its negative.

You multiply the fractions until the denominators are equal. Then, you subtract.

You need a common denominator for both.

They have to have the same denominator.

When adding or subtracting fractions their denominators must be the same

Ensure that the denominators are the same when adding or subtracting fractions.

Yes.

Pulled and mulled

Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.

By the definition of like fractions, the denominators are the same.

no answer

Yes

A Common Denominator

Yes.

First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).

Just multiply the two denominators of your fractions, the answer you get is a common denominator.

Subtracting a negative fraction is the same as adding its positive equivalent.
