The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 3 and 9.
LCM of 3 and 9 = 9
Number of girls = 8 u
Number of adults = 3 u
Number of more girls than adults
= 8 u - 3 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Total number of people
= 3 u + 8 u + 1 u
= 12 u
= 12 x 3
= 36
Answer(s): 36
