The yearbook club had a meeting. the meeting had 30 people, which is five-sixths of the club. how many people are in the club?

First step is assigning variables. Let's assign P as the number of people in the club. Then looking at the information given, we have: 
5/6 * P = 30

If you divide the sides by 5/6, which is the same as multiplying by 6/5, we get:
P = 6/5 * 30 = 36

I hope this helped, I tried to help but this is all I knew.

Your cleary not see the answer is 25

The first one is 2/3the second is 1/160the third is 4/125
