14 of the people are adults.
910 of the remainder are girls.
There are 17 more girls than adults.
How many people are there?
Adults |
Children |
1 x 10 |
3 x 10 |
|
Girls |
Boys |
|
9 x 3 |
1 x 3 |
10 u |
27 u |
3 u |
The number of children is the combined repeated identity.
Make the number of children the same by using LCM of 3 and 10.
LCM of 3 and 10 = 30
Number of girls = 27 u
Number of adults = 10 u
Number of more girls than adults
= 27 u - 10 u
= 17 u
17 u = 17
1 u = 17 ÷ 17 = 1
Total number of people
= 10 u + 27 u + 3 u
= 40 u
= 40 x 1
= 40
Answer(s): 40
