Question
Perform the operations. Then simplify, if possible.a. $\frac{x}{9}+\frac{2 x}{9}$b. $\frac{x}{9} \cdot \frac{2 x}{9}$c. $\frac{x}{9} \div \frac{2 x}{9}$
Step 1
Since they have the same denominator, we can simply add the numerators: \[\frac{x}{9}+\frac{2x}{9} = \frac{x+2x}{9} = \frac{3x}{9}\] Show more…
