Answer 1

$a) \frac{10}{100} \times 250 = \frac{10}{10} \times 25 = 1 \times 25 = 25$

$b) \frac{15}{100} \times 200 = 15 \times 2 = 30$

$c) \frac{20}{100} \times 70 = \frac{2}{1} \times 7 = 2 \times 7 = 14$

$d) \frac{30}{100} \times 240 = \frac{3}{1} \times 24 = 3 \times 24 = 72$

$e) \frac{12}{100} \times 125 = \frac{12}{4} \times 5 = 3 \times 5 = 15$

$f) \frac{14}{100} \times 150 = \frac{14}{10} \times 15 = \frac{14}{2} \times 3 = 7 \times 3 = 21$

$g) \frac{120}{100} \times 25 = \frac{120}{4} \times 1 = \frac{120}{4} = 30$

$h) \frac{150}{100} \times 32 = \frac{15}{10} \times 32 = \frac{15}{5} \times 16 = 3 \times 16 = 48$
