3x3 = 9 u |
37.5% =

3875% =
75100 =
34The number of male passengers at first and in the end remains unchanged. Make the number of male passengers the same. LCM of 3 and 1 is 3.
Number of female passengers who entered the terminal
= 9 u - 5 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Number of female passengers at the terminal at first
= 5 u
= 5 x 12
= 60
Answer(s): 60
