1. The proportion of lemon juice in a fruit drink is 250 ml in every litre.
Tom wants to make 3 litres of fruit drink.
a. How much lemon juice does he need?
b. How much fruit drink can be made from 2 litres of lemon juice?
A)1L=1000ml
3L=?ml (Cross multiply)
3 * 1000 = 3000ml
1
3000/250=12
=12 containers
1L=1000ml
2L=?ml (Cross multiply)
2 * 1000 =2000
1
2000/250=8
=8 containers
The second one is for question B
To find the answers, we need to use ratios and proportions.
a. To find how much lemon juice Tom needs for 3 litres of fruit drink, we use the given proportion: 250 ml of lemon juice in every litre of fruit drink.
To set up the proportion, we can write it as:
250 ml / 1 L = X ml / 3 L.
To solve this proportion, we can cross-multiply and divide:
250 ml * 3 L = X ml * 1 L,
750 ml = X ml.
So, Tom needs 750 ml of lemon juice for 3 liters of fruit drink.
b. To find how much fruit drink can be made from 2 liters of lemon juice, we need to first calculate the amount of fruit drink that corresponds to 2 liters of lemon juice.
Using the given proportion, we have:
250 ml / 1 L = X ml / 2 L.
Cross-multiplying and dividing:
250 ml * 2 L = X ml * 1 L,
500 ml = X ml.
So, from 2 liters of lemon juice, Tom can make 500 ml of fruit drink.
