Answer 1

$\frac{2}{3} = \frac{a}{6} = > 3 \times a = 2 \times 6$

$3 \times a = 12 \\ a = 12 \div 3 \\ a = 4$

$\frac{b}{5} = \frac{28}{10} = > 10 \times b = 5 \times 28$

$10 \times b = 1440 \\ b = 1440 \div 10 \\ b = 144$

$\frac{4}{c} = \frac{2}{9} = > 2 \times c = 4 \times 9$

$2 \times c = 36 \\2 \times c = 36 \\ c = 36 \div 2 \\ c = 18$

$\frac{12}{5} = \frac{24}{d} = > 12 \times d = 24 \times 5$

$12 \times d = 120 \\ d = 120 \div 12 \\ d = 10$
