The number of men in a trampoline park was
1315 that of the women. There were 140 more women than men. After some men left the trampoline park, the number of women in the trampoline park was five times the number of the remaining men. How many men left the trampoline park?

1x3 =
3 u |
5x3 =
15 u |
The number of women remain unchanged. Make the number of women the same. LCM of 15 and 5 is 15.
Number of more women than men
= 15 u - 13 u
= 2 u
2 u = 140
1 u = 140 ÷ 2 = 70
Number of men who left the trampoline park
= 13 u - 3 u
= 10 u
= 10 x 70
= 700
Answer(s): 700
