Answer 1

• a) 3

,

• b) 21

,

• c) Not enough information

Step-by-step explanation

Given

• 28 seniors

,

• 24 students went to the trip, where 7/8 were seniors.

Procedure

• a)

We are given the proportion of seniors, if we want to know the proportion of juniors we have to subtract it from 8/8 (whole):

`(8)/(8)-(7)/(8)=(1)/(8)`

Next, we have to multiply the students that went times the proportion:

`24\cdot(1)/(8)=3`

3 juniors went on the trip.

• b)

Now we have to multiply the proportion given times the students that went:

`24\cdot(7)/(8)=21`

Thus, 21 seniors went on the trip.

• c)

As we are not given the juniors that are in the class, we cannot answer this one.
