1 x 2 |
8 x 2 |

Girls |
Boys |

13 |
3 |
2 u |
13 u |
3 u |
The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 8 and 16.
LCM of 8 and 16 = 16
Number of girls = 13 u
Number of adults = 2 u
Number of more girls than adults
= 13 u - 2 u
= 11 u
11 u = 11
1 u = 11 ÷ 11 = 1
Total number of people
= 2 u + 13 u + 3 u
= 18 u
= 18 x 1
= 18
Answer(s): 18
