For

\frac{5}{4} :

multiply the denominator and numerator by

3

\frac{5}{4} = \frac{5 \cdot 3}{4 \cdot 3} = \frac{15}{12}

For

\frac{2}{3} :

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{15 + 8}{12}

Add the numbers:

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{23 + 21}{12}

Add the numbers:

23 + 21 = 44
