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?
As 100% means all of it, we can work out what percentage is not from carbohydrate by simply taking 60% away from 100%
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.
Hope this helps; let me know if I can do anything else:)
