Question

Carolina recorre 2/5 de km en 3/4 de hora. que distancia recorre en un 1/4 de hora

Answer 1

Regla de 3:

2/5 Km =======> 3/4 Hora
 
   X ==========> 1/4 Hora

X = [(2/5)(1/4)]/[3/4]

X = [(2x1)/(5x4)]/[3/4]

X = [2/20]/[3/4]

X = [1/10]/[3/4]

X = (4x1)/(3x10)

X = 4/30

X = 2/15

En 1/4 hora recorre 2/15 de Km
