A. X : 8 = 15 : 12 B. 6 : X = 21 : 49C. 18 : 21 = X : 28D. 28 : 49 = 32 : X

A. X : 8 = 15 : 12 B. 6 : X = 21 : 49C. 18 : 21 = X : 28D. 28 : 49 = 32 : X

Jawaban:

a. 10

b. 14

c. 24

d.56

Penjelasan dengan langkah-langkah:

$frac{x}{8} = frac{15}{12} \ x = frac{15 times 8}{12} = 10$

$frac{6}{x} = frac{21}{49} \ x = frac{49 times 6}{21} = 14$

$frac{18}{21} = frac{x}{28} \ x = frac{28 times 18}{21} = 24$

$frac{28}{49} = frac{32}{x} \ x = frac{32 times 49}{28} = 56$
