(b) 5 / 4 = (5/4 × 100) %

= 125%

(c) 3 / 40 = (3/40 × 100)%

= 7.5%

(d) 2 / 7 = (2/7 × 100) %

Answer 2

$(a) = \: \frac{1}{8} \times 100 \\ = \frac{25}{2}\% \\ = 12 \frac{1}{2} \% \\ (b) = \frac{5}{4} \times 100 \\ = (5 \times 25)\% \\ = 125\% \\ (c) = \frac{3}{40} \times 100 \\ = \frac{15}{2} \% \\ = 7 \frac{1}{2} \% \\ (d) = \frac{2}{7} \times 100 \\ = \frac{200}{7} \% \\ = 28 \frac{4}{7} \%$
