A club’s first meeting was attended by 72 people. Nine times as many people went to the first meeting than the second meeting. How many people attended the second meeting?

8 people attended the second meeting.

Step-by-step explanation:

Given that:

Number of people who attended the first meeting = 72

Let,

x be the number of people who attended second meeting.

9 times people of second meeting = Number of people who attended first meeting

9x = 72

Dividing both sides by 9

Hence,

8 people attended the second meeting.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
