Common Denominator

You must find a common denominator since you cannot add without a common denominator, There is no multiplication so you have to add/subtract.

$\frac{4}{5} - \frac{3}{9} + \frac{2}{3} - \frac{2}{5}$ $4/5 - 3/9 + 2/3 - 2/5$

The common denominator could be 45 so

$\frac{36}{45} - \frac{15}{45} + \frac{30}{45} - \frac{18}{45}$ $36/45 - 15/45 + 30/45 - 18/45$

This equation is then equal to $\frac{33}{45}$ $33/45$

How do you simplify 45−89+23−25\frac { 4} { 5} - \frac { 8} { 9} + \frac { 2} { 3} - \frac { 2} { 5}?
