Question

Ben makes orange paint by mixing red, yellow and white paint in the ratio 20 : 16 : 1.5. how much of each colour does he need to make 1.5 litres of orange paint?​

Answer 1

0.8L = red

0.64L = yellow

0.06L = white

Explanation:

R : Y : W

20 : 16 : 1.5

20 + 16 + 1.5 = 37.5

1.5 ÷ 37.5 = 0.04

0.04 × 20 = 0.8L = red

0.04 × 16 = 0.64L = yellow

0.04 × 1.5 = 0.06L = white
