Problema Urgente:

El Lunes gasto 1/3 de gasolina, de lo que sobro el martes gaste 2/3, y de lo que sobro el martes, el miercoles gaste 1/4. Y sobraron 200 ml. ¿Cuantos ml tenia antes?

PORFAVOR AYUDARME XDDD.

Answer 1

X - (1/3)X - (2/3)(1 - 1/3)X - (1/4)(1 - 2/3)(1 - 1/3)X = 200ml

X - (1/3)X - (2/3)(2/3)X - (1/4)(1/3)(2/3)X = 200ml

X - (1/3)X - (4/9)X - (1/18)X = 200ml

(1 - 1/3 - 4/9 - 1/18)X = 200ml

(1/6)X = 200ml

X/6 = 200ml

X = 1200ml
