After Mia gave 1/4 of her milk to Dante, he had twice as much milk as Mia had. What was the initial ratio of Mia’s milk to Dante’s milk?

1 Answer

  • Use two variables:

    M: initial milk quantity of Mia => quantity after she gave 1/4 of her milk to Dante = M - (1/4)M = 3M/4

    D: initial milk quantity of Dante => D + M/4 Dante's quantity after Mia gave him 1/4 of her Milk

    => 3M/4 = 2(D + M/4)

    You want the ratio M/D

    3M/4 = 2D + M/2

    3M/4 - M/2 = 2D

    3M/4 - 2M/4 = 2D

    M/4 = 2D

    M/D = 4*2

    M/D = 8

    Answer: M/D = 8
