Explicação passo-a-passo:

$3)calcule$

$a) \frac{3}{8} \times 40 = \frac{3 \times 40}{8 \times 1} = \frac{120}{8} = 15$

$b) \frac{2}{7} \times 63 = \frac{2 \times 63}{7 \times 1} = \frac{126}{7} = 18$

$c) \frac{4}{9} \times 72 = \frac{4 \times 72}{9} = \frac{288}{9} = 32$

$d) \frac{5}{11} \times 22 = \frac{110}{11} = 10$
