Question

6) Determine o valor de x na proporção abaixo:

a)3/8 = x/72. b) x/15 = 12/60​

Answer 1

a)3/8 = x/72

8x = 72×3

8x = 216

x = 216/8

x = 27

b) x/15 = 12/60

60x = 15×12

60x = 180

x = 180/60

x = 3

Explicação passo-a-passo:

a)

$\large\boxed{\begin{array}{l} \sf \dfrac{3}{8} = \dfrac{x}{72} \\ \\ \sf \: 8x = 72 \times 3 \\ \\ \sf \: 8x = 216 \\ \\ \sf \: x = \dfrac{216}{8} \\ \\ \boxed{ \boxed{ \boxed{ \sf{x = 27}}}} \checkmark\end{array}}$

b)

$\large\boxed{\begin{array}{l} \sf \dfrac{x}{15} = \dfrac{12}{6 0 } \\ \\ \sf \: 60x = 15 \times 12 \\ \\ \sf \: 60x = 180 \\ \\ \sf \: x = \dfrac{180}{60} \\ \\ \boxed{ \boxed{ \boxed{ \sf{x = 3}}}} \checkmark\end{array}}$
