Question

Add and express the sum in simplest form:

$\frac{7}{33}+\frac{4}{33}=\_\_\_$

Answer 1

• Step 1: As these are the like fractions, add the numerators and write the sum over the common denominator.

$\frac{7}{33}+\frac{4}{33}=\frac{7+4}{33}=\frac{11}{33}$

• Step 2: It can be observed that $11$ is the common factor of $11$ and $33$. Divide the numerator and denominator by the common factor $11$.

$\frac{11÷11}{33÷11}=\frac{1}{3}$

• Hence, the simplest form of $\frac{11}{33}$ is $\frac{1}{3}$.
