Question

Which of the following is a rational number equal to $\frac{4}{7}$ with 16 as the numerator?

• A. $\frac{16}{21}$
• B. $\frac{16}{28}$
• C. $\frac{16}{15}$
• D. $\frac{16}{20}$

Answer 1

The correct option is B

$\frac{16}{28}$

Consider the given rational number $\frac{4}{7}$.

To make the numerator as 16, we have to multiply it by 4.

Multiplying both numerator and denominator by 4, we get

$\frac{4\times 4}{7\times 4}=\frac{16}{28}$

Therefore, $\frac{16}{28}$ is an equivalent rational number of $\frac{4}{7}$ with numerator equal to 16.
