Answer 1

$a) \: 2 \times \frac{1}{3} = \frac{2}{3} \\ \\b) \: 8 \times \frac{3}{4} = \frac{24}{4} = 6 \\ \\ c) \: \frac{5}{6} \times 4 = \frac{20}{6} = \frac{10}{3} \\ \\ d) \: \frac{12}{40} \times 5 = \frac{60}{40} = \frac{3}{2} \\ \\ e) \: \frac{12}{40} \times 10 \times \frac{30}{18} = \frac{3}{10} \times 10 \times \frac{5}{3} = \frac{150}{30} = 5 \\ \\ f) \: 24 \times \frac{7}{18} \times \frac{1}{14} = 4 \times \frac{1}{3} \times \frac{1}{2} = \frac{4}{6} = \frac{2}{3}$
