Answer 1

Step-by-step explanation:

$(a) \: \: \: \: \frac{1}{8} \times 100$

$= \frac{1}{4} \times 50$

$= \frac{1}{2} \times 25$

$= \frac{25}{2}$

$= 12.5\%$

$(b) \: \: \: \: \: \frac{5}{4} \times 100$

$= \frac{5}{2} \times 50$

$= \frac{250}{2}$

$= 125\%$

$(c) \: \: \: \: \: \frac{3}{40} \times 100$

$= \frac{3}{4} \times 10$

$= \frac{3}{2} \times 5$

$= \frac{15}{2}$

$= 7.5\%$

$(d) \: \: \: \: \frac{2}{7} \times 100$

$= \frac{200}{7}$

$= 28.57\%$
