A group of friends went to the stampede fair. They bought 4 ride tickets each. Each ride ticket costs $2.75. What was the total cost of the ride tickets for each person?

Question: How do you find the answer?

• You add 2.75 + 4

• You subtract 2.75 - 4

• You multiply 2.75 x 4

• You divide 2.75 by 4

A group of friends went out for pizza. The total cost of the pizza was $32.25. If they split the cost equally among 5 friends, how much did each friend pay?

Question: How will you solve this question?

• You add 32.25 + 5

• You subtract 32.25 - 5

• You multiply 32.25 x 5

• You divide 32.25 by 5

A video game normally costs $45.00. It's on sale for 20% off. How much money will you save with the discount?

Question: How do you solve this question?

• You add $45 + 20.

• You subtract $45 - 20

• You divide 45 by 20

A group of students has 12 apples and 18 oranges. What is the simplified ratio of apples to oranges?

Question: How do you solve this question?

• You add apples + oranges

• You subtract oranges - apples

• You multiply apples and oranges by the same number

• You divide apples and oranges by the same number

Two clubs, the Mathletes and the Science Squad, are planning a joint fundraising event.

The Mathletes have 48 cookies to sell, and the Science Squad has 36 brownies to sell. They want to create identical treat bags, with each bag containing the same number of cookies and the same number of brownies. How many cookies or brownies could be in each treat bag?

Question: How do you solve this question?

• You add 48 and 36, then find the factors of the sum

• You subtract 48 - 36, then find the factors of the difference

• You list the factors of both numbers and find the ones that are the same

• You divide 48 and 36 by the same number.

Two buses leave the station at the same time. Bus A departs every 12 minutes, and Bus B departs every 18 minutes. How many minutes will pass before both buses leave the station together again?

Question: How do you solve this question?

• You add 12 + 8. That is the next time buses leave at the same time.

• You list multiples of 12 and 8. Where the numbers are the same, that is the next time the buses leave at the same time.

• You subtract 12-8. This is the interval at which the buses leave at the same time.

• You divide 12 and 8 by the same number. This is the interval in which the buses leave at the same time.

A spinner like the one shown is spun. List all the possible outcomes of this single event.

Question: How do you answer this question?

• List the possible colours that the spinner can land on.

• List the colour that appears the most.

• List the colours in order of likelihood of landing on them in fraction form.

• List the percentages of likelihood of landing on each colour.

A player's score in a video game changes as follows: +25 points, -18 points, -12 points, and +30 points. What is the player's final score?

Question: How do you solve this question?

• Add the postive numbers and add the negative numbers, then subtract the sums.

• Create an addition sentence and then solve it left to right.

• Add the positive numbers and then subtract the negative numbers and then find the sum of those.

• Add the positive numbers and then add the negative numbers and then find the difference of those.

A recipe calls for 1/8 cup of sugar and 3/8 cup of flour. How much total dry ingredients are needed?

Question: How do you solve this question?

• Add 1/8 to 3/8 and then simplify if possible.

• Subtract 3/8 - 1/8 and then simplify if possible.

• Multiply 3/8 by 1/8.

• Add 1/8 + 3/8. Done.

A painter used 3/4 of a gallon of blue paint and 1/3 of a gallon of red paint. How much more blue paint did the painter use than red paint?

Question: How do you solve this question?

• Add 3/4 + 1/3, then simplify the fraction if possible

• Subtract 3/4 - 1/3, then simplify the fraction if possible.

• Multiply 3/4 by 1/3, then simplify the fraction if possible.

• None of these.
