Atwo-way frequency table is shown below that displays the relationship between pizza type and pizza crust choices. we took a sample of 110 people and recorded the following results:
thin crust thick crust stuffed crust total
cheese pizza 3 9 13 25
all-meat pizza 5 15 25 45
hawaiian pizza 2 6 32 40
total 10 30 70 110
the restaurant is about to prepare pizza for a children's birthday party. knowing that the party planner only wants cheese pizza, what percentage (rounded to the nearest whole percent) of the order will be for stuffed-crust pizza?

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
