Question

Mr. Franklin asked each of his 30 students to

select their favorite radio station.
•1/3 of the students chose Station K.
. 1/5 of the students chose Station L.
• The remaining students chose Station M.
How many students chose Station M as their
favorite radio station?
A 10
B 14
C 6
D 4

Answer 1

14

Explanation:

30/3 = 10

30/5 = 6

10 + 6 = 16

30 - 16 = 14

Answer 2

B) 14

Explanation:

1/5 + 1/3 = x (don't worry, it's not algebra, I'm just using x as an example)

The common denominator is 15, so you multiply 5 by 3 = 15 and 1 by 3 = 3,

3/15 = 1/5

Then, multiply 3 by 5 = 15 and then 1 by 5 = 5, so it's

5/15 = 1/3

5/15 + 3/15 = 8/15 and then multiply 15 by 2 = 30 (number of students) and because you multiplied 15 by 2, you also multiply 8 by 2 = 16

So it is now 16/30, so you do 30-16 which is 14.

14 students chose Station M (doesn't sound like a good station).

Whoo! Let's go! (I'll stop being cringy now).
