Question

Numerele x,y si 16 sunt direct proportionale respectiv cu numerele 27, 36, si 48. Aflati numerele x si y

Answer 1

x=27k
y=36k
16=48k
k=1/3
x=27×1/3=9
y=36×1/3=12

Answer 2

x = 27k
y = 36k
16 = 48k
27 = 3 * 3 * 3
36 = 3 * 3 * 2 * 2
48 = 3 * 2 * 2 * 2 * 2 
k = 1/3
x = 27 * 1/3
x = 9
y = 36 * 1/3
y = 12
