A - b = 438
2.25 / 100 * a = 8,(3) / 100 * b
0.0225 * a = (83 - 8)/9 / 100 * b
0.0225 * a = 75/9 / 100 * b
0.0225 * a = 75/9*100 * b
0.0225 * a = 1/12 * b
0.0225 a = b / 12
0.0225 * 12 * a = b
0.27 a = b
a - 0.27 a = 438
0.73 a = 438
a = 438 / 0.73
a = 600
600 - b = 438
b = 162
Numerele sunt: 600 si 162.
