There were 231 adults enrolled in the Julie Acting School in 2015. ³₇ of the adults were men. Additional adults joined the acting school in 2016. For every 3 men who joined the acting school, 2 women joined the acting school. If there was an equal number of women and men in 2016, how many women joined the school in that year?

	Men	Women
Before	99	132
Change	+ 3 u	+ 2 u
After	99 + 3 u	132 + 2 u

Fraction of adults who are women
= 1 - ³₇
= ⁴₇

Number of men at first
= ³₇ x 231
= 99

Number of women at first
= ⁴₇ x 231
= 132

Men who joined : Women who joined
3 : 2

The number of women and men in the end is the same.

99 + 3 u = 132 + 2 u
3 u - 2 u = 132 - 99

1 u = 33

Number of women who joined the school in that year
= 2 u
= 2 x 33
= 66

Answer(s): 66
