Diketahui

(1/2) = (3/x)

x = 6

(3/4) = (6/y)

3y = 24

y = 24/3

y = 8

(5/6) = (z/12)

60 = 6z

z = 60/6

z = 10

Nilai x + y + z

= 6 + 8 + 10

= 14 + 10

= 24 (C)

$sf frac{1}{2} = frac{3}{x}$

$sf : x = 3 times 2$

$sf : x = 6$

$sf frac{3}{4} = frac{6}{y}$

$sf frac{6}{8} = frac{6}{y}$

$sf : y = 8$

$sf frac{5}{6} = frac{z}{12}$

$sf frac{10}{12} = frac{z}{12}$

$sf : z = 10$

maka

x + y + z

= 6 + 8 + 10

= 14 + 10

= 24
