Answer 1

$\frac{1}{4} + \frac{1}{4} : ( \frac{1}{4} + \frac{1}{4} \times \frac{1}{2}) \times \frac{3}{4} = \frac{1}{4} + \frac{1}{4} : ( \frac{1}{4} + \frac{1 \times 1}{4 \times 2}) \times \frac{3}{4} = \frac{1}{4} + \frac{1}{4} : ( \frac{1}{4} + \frac{1}{8}) \times \frac{3}{4} = \frac{1}{4} + \frac{1}{4} : \frac{3}{8} \times \frac{3}{4} = \frac{1}{4} + \frac{1}{4} \times \frac{8}{3} \times \frac{3}{4} = \frac{1}{4} + \frac{1 \times 8 \times 3}{4 \times 3 \times 4} = \frac{1}{4} + \frac{24}{48} = \frac{1}{4} + \frac{1}{2} = \frac{3}{4}$
