Answer: C. 12/28
Explanation:
When multiplying fractions, you multiply the numerator by the second fraction's numerator (a numerator is the top number in the fraction), and the denominator (a denominator is the bottom number in the fraction) by the second fraction's denominator.
For example:
4 (numerator of fraction 1) x 3 (numerator of fraction 2) = 12
4 (denominator of fraction 1) x 7 (denominator of fraction 2) = 28
So, the final product would be 12/28.
