(1)
Given the statement: A zoo has 17 monkeys and 12 chimpanzees
Write this situation in three ways, comparing the first quantity to the second quantity.
By definition of ratio:
Ratio in three ways are:
17 to 12
17 : 12
or we can write this as 17 over 12.
therefore, Option B is correct.
(2)
As per the statement: In Largo City, about one in every nine homes contains four televisions
Write this situation in three ways in the form of ratio, comparing the first quantity to the second quantity.
By definition of ratio:
Ratio in three ways are:
4 to 9
4 : 9
therefore, only options C is correct.
(3)
write three ratios for 7 over 35
By definition of ratio;
We have;
Divide both numerator and denominator by 7 we have;
.....[A]
⇒
Multiply both numerator and denominator by 2 in A we get;
Similarly,
Multiply both numerator and denominator by 3 in A, we get
Therefore, 3 ratios equal to 7 over 35 are;
or we can write it as one-fifth
or two -tenths
or three over fifteen
hence, Option D is correct.

Given the statement: Jake sold 28 tickets to the school fair, and Jeanne sold 21 tickets
Number of ticket Jake sold = 28 ticket.
Number of ticket Jeanne sold = 21 ticket.
To find: Number of ticket Jeanne sold to number of ticket Jake sold.
By definition of ratio
⇒
Therefore, the ratio in simplest form is,
Answer:
Approximately (
.) (Assume that the choices of the
passengers are independent. Also assume that the probability that a passenger chooses a particular floor is the same for all
floors.)
Step-by-step explanation:
If there is no requirement that no two passengers exit at the same floor, each of these passenger could choose from any one of the
floors. There would be a total of
unique ways for these
passengers to exit the elevator.
Assume that no two passengers are allowed to exit at the same floor.
The first passenger could choose from any of the floors.
However, the second passenger would not be able to choose the same floor as the first passenger. Thus, the second passenger would have to choose from only floors.
Likewise, the third passenger would have to choose from only floors.
Thus, under the requirement that no two passenger could exit at the same floor, there would be only unique ways for these two passengers to exit the elevator.
By the assumption that the choices of the passengers are independent and uniform across the floors. Each of these
combinations would be equally likely.
Thus, the probability that the chosen combination satisfies the requirements (no two passengers exit at the same floor) would be:
