Answer to Question #293260 in Algebra for Nana

Question

To make a certain drink you need to mix 200 millimeters of concentrate with 1.2litres of water. Determine the ratio of concentrate to water how much concentrate will you need if you make up a total of 14 litres of this drink

Answer 1

If we take 200 millilitres of concentrate with 1.2litres of water, we make up $0.2+1.2=1.4$ litres of this drink.

We need to increase the amount of ingredients in $14/1.4=10$ times to make up $14$

litres of this drink.

$$0.2\cdot10=2(litres)$$

$$1.2\cdot10=12(litres)$$

We need to mix 2 litres of concentrate with 12litres of water make up a total of 14 litres of this drink.

The ratio concentrate to water is $1:6.$
