Example Question #292 : How To Multiply Fractions

Solve:

\(\displaystyle \small \frac{4}{8}\times\frac{3}{4}\)

Possible Answers:

\(\displaystyle \small \frac{2}{3}\)

\(\displaystyle \small \frac{1}{2}\)

\(\displaystyle \small \frac{3}{8}\)

\(\displaystyle \small \frac{1}{4}\)

\(\displaystyle \small \frac{7}{9}\)

Correct answer:

\(\displaystyle \small \frac{3}{8}\)

Explanation:

When we multiply fractions, we multiply the numerator by the numerator and the denominator by the denominator. 

\(\displaystyle \small \small \frac{4}{8}\times\frac{3}{4}=\frac{12}{32}\)

\(\displaystyle \small \frac{12}{32}\) can be reduced by dividing both sides by \(\displaystyle \small 4\)

\(\displaystyle \small \frac{12}{32}\div\frac{4}{4}=\frac{3}{8}\)
