Answer 1

Resposta:

Explicação passo-a-passo:

a)

$\frac{12}{3} = \frac{10}{x}\\\\12x = 30\\x= \frac{30}{12} = \frac{10}{4} = \frac{5}{2}$

b)

$\frac{32}{6} = \frac{20}{x}\\\\32x = 120\\x = \frac{120}{32} = \frac{60}{16}= \frac{15}{4}$

c)

$\frac{4}{2} =\frac{10}{x}\\\\4x = 20\\x = 5$

d)

$\frac{3}{30} = \frac{270}{x}\\\\3x = 8100\\x= \frac{8100}{3} = 2700$

e)

$\frac{4}{3} = \frac{4}{x}\\\\4x = 12\\x = 3$
