Different Denominators

Add or subtract whole numbers first

Are the denominators the same?

If yes then add or subtract the numerators

If no then use equivalent fractions to make them the same, then add or subtract numerators (the denominator stays the same)

simplify the answer if possible

Example:

1) 4/5 + 3/10

=8/10 + 3/10

=11/10

= 1 1/10
