Answer 1

Resposta:

a) x/3 = 24/6

6x = 72

x = 72/6

x = 12

b) 8/y = 50/25

 200 = 50y

y = 200/50

y = 4

c) 1/4 = 7/z

1z = 28

z = 28

d) 6/7 = w/21

126 = 7w

w = 126/7

w = 18

Answer 2

Resposta:

a) x = 12

b) y = 4

c) z = 28

d) w = 18

Explicação passo-a-passo:

a) $\frac{x}{3} = \frac{24}{6}$ -> (multiplique cruzado) 6x = 72 -> x = 72 : 6 -> x = 12

b) $\frac{8}{y} = \frac{50}{25}$ -> 50y = 200 -> y = 200 : 50 -> y = 4

c) $\frac{1}{4} = \frac{7}{z}$ -> 1z = 28 -> z = 28 : 1 -> z = 28

d) $\frac{6}{7} = \frac{w}{21}$ -> 7w = 126 -> w = 126 : 7 -> w = 18
