Answer 1

$\frac{1}{5} \times 100 = 20$

$\frac{1}{5} \times 105 = 21$

$\frac{1}{5} \times 110 = 22$

$\frac{2}{3} \times 624 \\ 2 \times 208 = 416$

$\frac{2}{3} \times 1248 \\ 2 \times416 = 832$

$\frac{2}{3} \times 2496 \\ 2 \times 832 = 1664$

$\frac{3}{7} \times 840 \\ 3 \times 120 = 360$

$\frac{4}{7} \times 840 \\ 4 \times 120 = 480$

$\frac{5}{7} \times 840 \\ 5 \times 120 = 600$
