John has 500ml of apple juice. he wants to mix apple juice with fizzy water in the ratio 1: 10. fizzy water is sold in 1500ml bottles. work out the smallest number of bottles of fizzy water needed to mix all the apple juice

First, calculate the amount of fizzy water John will need. If the ratio of apple juice to water is 1:10, then you can multiply the volume of apple juice by 10 to get the volume of fizzy water needed.

500mL x 10 = 5,000mL of fizzy water

Divide 5,000mL of fizzy water by 1,500 to get 3.33...

The minimum number of soda bottles that John will need to buy is 4, because you can't buy a third of a bottle.

Hope this helped!
