At a parade,
47 of the people who attended were adults.
45 of the remainder were girls and the rest were boys. If there were 255 more adults than boys, how many people attended the parade?
| Adults |
Children |
4x5 =
20 u |
3x5 =
15 u |
| |
Girls |
Boys |
| |
5x3 =
15 u |
| |
4x3 =
12 u |
1x3 =
3 u |
| 20 u |
12 u |
3 u |
The number of children is the combined repeated identity. Make the number of children the same. LCM of 3 and 5 is 15.
Number of more adults than boys
= 20 u - 3 u
= 17 u
17 u = 255
1 u = 255 ÷ 17 = 15
Number of people who attended the parade
= 20 u + 15 u
= 35 u
= 35 x 15
= 525
Answer(s): 525
