Responder:

Número total de bolas = 245/23

Explicación paso a paso:

Dado que:

Bolas blancas = 1/5

Bolas negras = 1/7

Bolas rojas = 7

Sea el número total de bolas = x

Bolas blancas = 1 / 5x

Bolas negras = 1 / 7x

Por tanto, total;

(x / 5 + x / 7 + 7) = x

((7x + 5x) / 35) +7 = x

(12x / 35) + 7 = x

7 = x - 12x / 35

7 = (35x - 12x) / 35

7 = 23 veces / 35

245 = 23x

x = 245/23
