Question

To generate equivalent fractions of a given fraction, we can _________ the numerator and denominator by the same number.
(Note: There can be more than one correct answer.)

• A. multiply
• B. divide
• C. subtract
• D. add

Answer 1

Answer: (A), (B)

divide

To generate equivalent fractions of a given fraction, we can multiply or divide the numerator and denominator by the same number.
$\frac{1\times 2}{5\times 2}=\frac{2}{10}$
$\frac{1}{5}$ is equivalent to $\frac{2}{10}$
$\frac{3÷3}{15÷3}=\frac{1}{5}$
So, $\frac{3}{15}$ is equivalent to $\frac{1}{5}$
So, both option C and option D are correct.
