4 x 3 |
3 x 3 |
7 u |
12 u |
9 u |
The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 3 and 7.
LCM of 3 and 7 = 21
Number of boys = 12 u
Number of adults = 7 u
Number of more boys than adults
= 12 u - 7 u
= 5 u
5 u = 10
1 u = 10 ÷ 5 = 2
Total number of people
= 7 u + 12 u + 9 u
= 28 u
= 28 x 2
= 56
Answer(s): 56
