A fitness club offers a hip-hop dance class and a step-dance class. There are currently 13 people in the hip-hop class, and attendance is increasing by 9 people per month. There are currently 37 people in the step-dance class, and attendance is increasing by 6 people per month. After how many months will there be the same number of people in each class?
+9481 Let's call the number of months that have passed " m " .
num. of people in hip-hop class = 13 + 9m
num. of people in step-dance class = 37 + 6m
What is " m " when num. of people in hip-hop class = num. of people in step-dance class ?
What is " m " when 13 + 9m = 37 + 6m ?
13 + 9m = 37 + 6m Subtract 6m from both sides of the equation.
13 + 3m = 37 Subtract 13 from both sides of the equation.
3m = 24 Divide both sides by 3.
m = 8
After 8 months, there will be the same number of people in each class. :)
....However.....instead of the two classes competing, maybe they should join together, like this?

I have your answer.
Next time, plz do your homework on your own, and dont ask it at a math website! Would you like your parents or teacher or whoever gave you this problem to know you cheated? I didn't think so. Even if you arent cheating on something, you must not be very good at math if you cant solve this!
I would just find two multiples of 6 and 9 that have differences of 24. Then, add 37 to the multiple of 6 and 13 to the multiple of 9. Simple? Ask a real person next time instead of having to resort to electronics.

Gee, Guest....take a Valium......!!!!
Everyone isn't endowed with your superior math abilities.......
However.......until you have some famous theorem named in your honor, we'll continue to try to help the great unwashed.....
