Question

Find the sum of $\frac{1}{18}$ and $\frac{1}{18}$.

• A. $\frac{1}{9}$
• B. $\frac{2}{9}$
• C. $\frac{1}{3}$
• D. $\frac{6}{9}$

Answer 1

The correct option is A

$\frac{1}{9}$

Fractions with same denominators can be added by simply adding the numerators and writing the common denominator as it is.

$\frac{1}{18}+\frac{1}{18}=\frac{1+1}{18}=\frac{2}{18}=\frac{2÷2}{18÷2}=\frac{1}{9}$
