Work Step by Step

You are given the following: $a=\frac{1}{2}$ $b=\frac{3}{4}$ You are solving for $ab$ or $a\times b$, and since you have the values for both $a$ and $b$, you can plug them in: $\frac{1}{2}\times \frac{3}{4}$ To multiply fractions, you first multiply the numerators--the "numbers on top". The result will be the numerator of your answer. $1\times3=3$ Then you multiply the denominators--the "numbers on bottom." The result will be the denominator of your answer. $2\times4 =8$ Therefore, the final answer will be $\frac{3}{8}$.
