A shop sells chocolate, vanilla and strawberry ice creams. 45% of the ice creams sold are vanilla, and 17% are strawberry. What percentage are chocolate?

38% are chocolate

Step-by-step explanation:

If a shop that sells ice cream only has chocolate, vanilla and strawberry flavors, then the total percentage of ice cream they sell should add up to 100%. Since 45% sold are vanilla and 17% sold are strawberry, we can find the percentage of chocolate by subtracting these values from our total of 100%:

100 - 45 - 17 = 38

So, the remaining 38% of ice cream sold must be chocolate.
