3-62.

Add or subtract the following fractions.

1. $\frac { 2 } { 3 } - \frac { 5 } { 12 }$

• 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 $12$.

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

$\frac{8}{12}-\frac{5}{12}=\frac{3}{12}=\frac{1}{4}$
$\frac{1}{4}$
1. $\quad \frac { 4 } { 5 } + \frac { 11 } { 12 }$
