Question

1. $\frac{1}{3} + \frac{1}{9} =$

Explanation:

Step1: Find a common denominator

The denominators are 3 and 9. The least common denominator is 9. Rewrite $\frac{1}{3}$ with denominator 9: $\frac{1}{3}=\frac{1\times3}{3\times3}=\frac{3}{9}$

Step2: Add the fractions

Now add $\frac{3}{9}$ and $\frac{1}{9}$: $\frac{3}{9}+\frac{1}{9}=\frac{3 + 1}{9}=\frac{4}{9}$

Answer:

$\frac{4}{9}$
