Boys |
Girls |

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 boys = 7 u
Number of adults = 3 u
Number of more boys than adults
= 7 u - 3 u
= 4 u
4 u = 28
1 u = 28 ÷ 4 = 7
Total number of people
= 3 u + 7 u + 2 u
= 12 u
= 12 x 7
= 84
Answer(s): 84
