3liters of juice to the ratio 5:3:4

Radda [10]

Step-by-step explanation:

Let 3 litres of juice be divided into 5x, 3x and 4x parts.

$\therefore \: 5x + 3x + 4x = 3 \: litres \\ \therefore \: 12x = 3000 \: ml\\ \therefore \: x = \frac{3000}{12} \\ \therefore \: x = 250 \: ml \\ \therefore \: \\ 5x = 5 \times 250 = 1250 \: m = 1.25 \: l \\ 3x = 3\times 250 = 750 \: ml = 0.75 \: l\\ 4x = 4 \times 250 = 1000 \: ml = 1 \: l\\$
