  1. = $\frac{1}{3}$ – $\frac{3}{4}$ + $\frac{3}{5}$ + $\frac{1}{64}$ – $\frac{2}{9}$ – $\frac{1}{36}$ + $\frac{1}{15}$ 

    = $\frac{1}{3}$ – $\frac{2}{9}$ + $\frac{3}{5}$ + $\frac{1}{15}$ – $\frac{3}{4}$ – $\frac{1}{36}$ + $\frac{1}{64}$

    = $\frac{1}{9}$  + $\frac{10}{15}$ – $\frac{28}{36}$ + $\frac{1}{64}$ 

    = $\frac{1}{9}$  + $\frac{2}{3}$ – $\frac{7}{9}$ + $\frac{1}{64}$

    = $\frac{-6}{9}$ + $\frac{2}{3}$ + $\frac{1}{64}$

    = $\frac{1}{64}$
