Answer 1

$4 \times \frac{1}{4} + \frac{1}{2} \div \frac{3}{4} - \frac{1}{4} \times 4 \times \frac{1}{2} \ \\ \\ \ = 1 + \frac{1}{2} \div \frac{(4 \times 3) - (4 \times 1)}{(4 \times 4)} \times 2 \ \ \\ \\ \ \ = 1.5 \div \frac{(12 - 4)}{(16)} \times 2 \\ \\ = 1.5 \div \frac{8}{16} \times 2 \\ \\ = 1.5 \times \frac{(8 \times 2)}{(16)} \\ \\ = 1.5 \div \frac{16}{16} \\ \\ = 1.5 \div 1 \\ \\ = 1.5 = \frac{3}{2}$
