Answer 1

$1) \: \frac{2}{5} = \frac{4}{10} \\ 2) \: \frac{4}{9} = \frac{8}{18} \\ 3) \: \frac{100}{40} = \frac{10}{4}$

$4) \frac{4}{3} = \frac{8}{x} \\ 4x = 8 \times 3 \\ 4x = 24 \\ x = \frac{24}{4} \\ x = 6$

$5) \frac{4}{19} = \frac{20}{m} \\ 4m = 19 \times 20 \\ 4m = 380 \\ m = \frac{380}{4} \\ m = 95$

$6) \frac{63}{45} = \frac{g}{15} \\ 63 \times 15 = 45g \\ 945 = 45g \\ \frac{945}{45} = g \\ 21 = g$
