Question

3
Colette makes a fruit punch. The ratio of orange juice
to lemonade to grapefruit juice is 4:7:3.
She keeps the quantities in direct proportion. How
much lemonade does she need if she uses:
(a) 400 ml of orange juice
(b) 6 litres of grapefruit juice
(c) 120 ml of grapefruit juice?​

Answer 1

Answer:

(a)700 ml of lemonade

(b)14 ml of lemonade

(c)280 ml of lemonade

Step-by-step explanation:

at first for 400 ml of orange juice, we see that the lemonade is required in ratio of 4:7 so if we take amount of lemonade to be x then, 400/x=4/7 and by

further simplification we find out that the result is 700 ml just like this we can find out the remaining parts of the question.
