Harry, a 6th grader, started a collection
of sports cards with a few cards. His
best friend gave him 2 more cards.
About a week later, Harry got a soda
cap reward of 3 times the number of
sports cards in his collection. He
decided he should share his good
fortune with his best friend and gave
him 10 of his new cards and kept 11
for himself. How many cards did Harry
start his collection with?

the answer is 62

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
