Answer

• a) 3

,

• b) 21

,

• c) Not enough information

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):

$\frac{8}{8}-\frac{7}{8}=\frac{1}{8}$

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

$24\cdot\frac{1}{8}=3$

3 juniors went on the trip.

• b)

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

$24\cdot\frac{7}{8}=21$

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.
