The number of women in a bowling alley was
59 that of the men. There were 200 more men than women. After some women left the bowling alley, the number of men in the bowling alley was five times the number of the remaining women. How many women left the bowling alley?

3x3 =
9 u |
The number of men remain unchanged. Make the number of men the same. LCM of 9 and 3 is 9.
Number of more men than women
= 9 u - 5 u
= 4 u
4 u = 200
1 u = 200 ÷ 4 = 50
Number of women who left the bowling alley
= 5 u - 3 u
= 2 u
= 2 x 50
= 100
Answer(s): 100
