Answer:

Sean got 63/81 questions right as a fraction.

Step-by-step explanation:

Sean got 63/81 correct. If there was a total of 81 questions, you put that as your denominator.

Now ask yourself: Can you simplify?

Yes you can.

You divide each number from the fraction by 9.

63 / 9 = 7

81 / 9 = 9

7/9 questions that Sean got correct.

If you also want a percentage + grade, Sean would get 77% which would be a C+

Step-by-step explanation:

We are asked in the above question to find the most number of cookies that would be in the bag.

We solve the above question using the Greatest Common Factor method

We find the factors of 16, 24, 32

The factors of 16 are: 1, 2, 4, 8, 16

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

The factors of 32 are: 1, 2, 4, 8, 16, 32

Then the greatest common factor is 8.

Therefore, the most number of each type of cookie that will be in the bag is 8 cookies
