Answer
a.) $\frac{1}{15}$
b.) $\frac{35}{24}$
Work Step by Step
a.) $\frac{2}{3}$ - $\frac{3}{5}$
Least Common Denominator of 3 and 5 = 15
Therefore, $\frac{10}{15}$ - $\frac{9}{15}$ = $\frac{1}{15}$
b.) 1 + $\frac{5}{8}$ - $\frac{1}{6}$
Least Common Denominator of 1, 8, and 6 = 24
Therefore, $\frac{24}{24}$ + $\frac{15}{24}$ - $\frac{4}{24}$ = $\frac{35}{24}$
