Si a / 7 = b / 13 = c / 12 y a + b + c = 192, hallar hallar el valor de a + b?
Si a / 7 = b / 13 = c / 12 y a + b + c = 192, hallar hallar el valor de a + b.
En resumen
Se le pone una constante 7K = a 13K = b 12K = c 7k / 7 = K 13K / 13 = K 12K / 12 = K K = K = K Si a + b + c = 192 32K = 192 K = 6 Hallar a + b a = 7K = 7. 6 = 42 b = 13K = 13. 6 = 78 a + b = 120 *.

Se le pone una constante
7K = a
13K = b
12K = c
7k / 7 = K 13K / 13 = K 12K / 12 = K
K = K = K
Si a + b + c = 192
32K = 192
K = 6
Hallar a + b
a = 7K = 7.
6 = 42
b = 13K = 13.
6 = 78
a + b = 120 *.
