In the chamber of commerce,

66 2/3 % of the members are women's and 200 of the member are men. How many chamber of commerce members are there in all?

We first find out what 1% of the members are.

66 2/3 % in its decimal fraction is 66.66

Let the number represented by 1% be x

66.66% = 200

1 % = x

We simplify the above equation.

66.66 * x = 200 x1

66.66x = 200

x = 200/66.66

x = 3.0003 → x = 3.0 rounded off.

So is if 1% represents 3,

then 100% will be 100% * 3 = 300

Therefore there are 300 chamber of commerce members.
