Answer

$\frac{3}{12}$ or $\frac{1}{4}$

Work Step by Step

$x=\frac{1}{3}$ $y= \frac{3}{4}$ $xy= \frac{1}{3} \times \frac{3}{4}$ $\frac{1}{3} \times \frac{3}{4}= \frac{1\times 3}{3\times 4}= \frac{3}{12}$ $ \frac{3\times 1}{3\times 4}$ Simplify the fraction. Cancel the common factor, which is 3. $\frac{3}{12}= \frac{1}{4}$
