Question

Write each of the following in lowest terms:

$\frac{15}{75}=\_\_\_$

Answer 1

• Step 1: It can be observed that $3$ is the common factor of $15$ and $75$. Divide the numerator and denominator by the common factor $3$.

$\frac{15÷3}{75÷3}=\frac{5}{25}$

• Step 2: Again, there is a common factor of $5$ and $25$ that is $5$. Divide the numerator and denominator of the obtained fraction $\frac{5}{25}$ by $5$.

$\frac{5÷5}{25÷5}=\frac{1}{5}$

• Hence, the simplest form of $\frac{15}{75}$ is $\frac{1}{5}$.
