\frac{51}{64}

Solution steps

1 - \frac{1}{4} + \frac{1}{16} - \frac{1}{64}

Follow the PEMDAS order of operations

Add and subtract (left to right)

1 - \frac{1}{4} = \frac{3}{4}

= \frac{3}{4} + \frac{1}{16} - \frac{1}{64}

\frac{3}{4} + \frac{1}{16} = \frac{13}{16}

= \frac{13}{16} - \frac{1}{64}

\frac{13}{16} - \frac{1}{64} = \frac{51}{64}

= \frac{51}{64}
