The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 5 and 15.
LCM of 5 and 15 = 15
Number of boys = 14 u
Number of adults = 3 u
Number of more boys than adults
= 14 u - 3 u
= 11 u
11 u = 11
1 u = 11 ÷ 11 = 1
Total number of people
= 3 u + 14 u + 1 u
= 18 u
= 18 x 1
= 18
Answer(s): 18
