Add and subtract fractions

Addition and Subtraction of Fractions

To addfractions with the same denominator, we simply add the numerators.

3/10+5/10=8/10

To add fractions with different denominators we first make equivalent fractions until we have common denominators. Then add the numerators!

1/2+4/5=13/10=

1/2=5/10

4/5=8/10

5/10+8/10=13/10=1_3/10

To subtract fractions

To subtract fractions with common denominators we simply subtract the numerators. If they have different denominators we need to find an equivalent fraction first.

6/5-3/5=3/5

11/12-1/6=

1/6=2/12

11/12-2/12=9/12=3/4


So basically

So Basically…..

  • Make equivalent fractions with common demominators

  • Add or subtract the whole numbers and numerators (leave the denominators alone!!!)
