If 40% of the people at the gym are women, then how many people are at the gym if there are 12 women?

There are 30 total people in the gym.

Use this proportion:

40 12

=

100 x

40% is the same thing as 40/100 which can be simplified to 2/5.

2 12

=

5 x

2 x 6=12

Since you multiply 2 by 6 to get 12 you have to do the same thing for 5. > 5x6=30

2 12

=

5 30

There you go! There are 30 total people in the gym. Thats your answer.

Hope this helps! :)
