I wonder if theres any other earths
2 of 3 parts of the club is 18 people. If we break 18 into 2 groups, we get 9 members in each group, meaning that 1 of the 3 parts of the club is 9 people. Since we have 2/3 present, we are missing 1/3, or 9 people, meaning there are 27 total members.
What’s the answer is the answer
32.6M/0.131=248.85M would be the population. It’s just “13.1% of x is 32.6M”.
