1 x 3 |
9 x 3 |

Girls |
Boys |

26 |
1 |
3 u |
26 u |
1 u |
The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 9 and 27.
LCM of 9 and 27 = 27
Number of girls = 26 u
Number of adults = 3 u
Number of more girls than adults
= 26 u - 3 u
= 23 u
23 u = 23
1 u = 23 ÷ 23 = 1
Total number of people
= 3 u + 26 u + 1 u
= 30 u
= 30 x 1
= 30
Answer(s): 30
