Step-by-step explanation:

$a = \frac{1}{2} \\ \\ b = \frac{3}{4} \\ \\ \\ \\ i) \: a \times b = \frac{1}{2} \times \frac{3}{4} = \frac{3}{8} \\ \\ \\ \\ ii) \: a + b = \frac{1}{2} + \frac{3}{4} = \frac{1 \times 2}{2 \times 2} + \frac{3 \times 1}{4 \times 1} \\ \\ \frac{2}{4} + \frac{3}{4} = \frac{2 + 3}{4} = \frac{5}{4} \\ \\ \\ \\ iii) \: 2a - b = 2( \frac{1}{2} ) - \frac{3}{4} = 1 - \frac{3}{4} \\ \\ = \frac{4}{4} - \frac{3}{4} = \frac{4 - 3}{4} = \frac{1}{4} \\ \\ \\ \\ iv) \: 2b + a = 2( \frac{3}{4}) + \frac{1}{2} = \frac{3}{2} - \frac{1}{2} \\ \\ = \frac{3 - 1}{2} = \frac{2}{2} = 1$
