me ajudemk

Answer 1

Resposta:

f) $\frac{3}{8}$

g) $\frac{1}{32}$

Explicação passo-a-passo:

f)

$\frac{1}{2} - (\frac{1}{4}-\frac{1}{8})\\\\ \frac{1}{2} - (\frac{2-1}{8})\\\\\frac{1}{2} - (\frac{1}{8})\\\\\frac{4-1}{8} =\frac{3}{8}$

g)

$(\frac{1}{2}-\frac{1}{4})\frac{1}{8}\\\\(\frac{2-1}{4} )\frac{1}{8}\\\\(\frac{1}{4} )\frac{1}{8} = \frac{1}{32}$
