The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 4 and 12.
LCM of 4 and 12 = 12
Number of girls = 11 u
Number of adults = 3 u
Number of more girls than adults
= 11 u - 3 u
= 8 u
8 u = 24
1 u = 24 ÷ 8 = 3
Total number of people
= 3 u + 11 u + 1 u
= 15 u
= 15 x 3
= 45
Answer(s): 45
