Mr. Franklin asked each of his 30 students to
denpristay [2]

Answer:

B) 14

Step-by-step 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).
