A cocktail has the ratio 2 parts orange juice to 5 parts lemonade.
If you have 7 litres of orange juice to use, how much lemonade do
you need?

Respuesta :

Answer:

17.5

Step-by-step explanation:

You can divide both the 2 parts of orange juice and the 5 parts of lemonade by 2, which is the smaller number of the both of them. Now you know that for 1 part of orange juice, you have 2.5 parts of lemonade. To convert it to litres proportionally, multiply each value by 7 (as is given).

1 x 7 = 7 litres orange juice

2.5 x 7 = 17.5 litres lemonade
