Ashop sells chocolate, vanilla and strawberry ice creams. 45% of the ice creams sold are vanilla, and 1/4 are strawberry. what percentage are chocolate?

30%

Step-by-step explanation:

Since we want percentage, we need to convert 1/4th to percentage first.

We will divide, get decimal, and then multiply by 100 to get percentage.

1/4 = 0.25

0.25 * 100 = 25%

Now, we can say:

45% + 25% + chocolate = 100%

70% + chocolate = 100%

chocolate = 100 - 70 = 30

Chocolate = 30%

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
