What is the least common multiple of $3$ and $12$? How can this help you with this calculation?

Convert two-thirds to a fraction with a denominator of $12$.

$\left ( \frac{2}{3} \right )\left ( \frac{4}{4} \right )=\frac{8}{12}$

Subtract five-twelfths from your answer to Step 1.

$\frac{8}{12}-\frac{5}{12}=\frac{3}{12}=\frac{1}{4}$

$\frac{1}{4}$

See the steps in part (a) for help. In this problem, you might need to rewrite both fractions so that they have a common denominator.
