( 2$\frac{5}{8}$ + $\frac{1}{2}$ ) : $\frac{15}{16}$ - 2
= ( $\frac{21}{8}$ + $\frac{1}{2}$ ) x $\frac{16}{15}$ - 2
= ( $\frac{21}{8}$ + $\frac{4}{8}$ ) x $\frac{16}{15}$ - 2
= $\frac{25}{8}$ x $\frac{16}{15}$ - 2
= $\frac{25 X 16}{8 X 15}$ - 2
= $\frac{5 X 2}{3}$ - 2
= $\frac{10}{3}$ - 2
= $\frac{10}{3}$ - $\frac{6}{3}$
= $\frac{4}{3}$
= 1$\frac{1}{3}$
