Question

Tyrese purchased a container of juice that contains 220 calories. The label says that 60% of the calories are from carbohydrates. How many calories are not from carbohydrates?

Answer 1

88 calories

Explanation:

As 100% means all of it, we can work out what percentage is not from carbohydrate by simply taking 60% away from 100%

`100% - 60% = 40%`

Then, to work out the amount of calories, we work out 40% of 220. This could be done by turning 40 to a decimal (40/100 = 0.4) and multiplying it by 220, or it could be done by working out 10% by dividing 220 by 10, then multiplying it by 4.

`40% = 0.4 )`
`220 xx 0.4 = 88`

or

`10% " of " 220 = 220/ 10 = 22`
`40% = 10% xx 4 = 22 xx 4 = 88`

`88` of the `220` calories are not from carbohydrate.

Hope this helps; let me know if I can do anything else:)
