The ratio of adult cats to kittens at a pet care center on Monday was 4:3. There were 15 kittens there that day. Saturday, 21 adult cats were at the pet care center. What is the difference between the number of adult cats at the pet care center on Saturday and Monday?

At dinner, 2/5 of the people had fish and 1/3 had chicken. if everyone else had lamb, what fraction of the people had lamb? and if 40 people had lamb , calculate the total number of people at the dinner.

1- 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.2- 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 the first question?

Me. i can't figure out this question. give an explanation too. .
