Raeann has 3 times as many wafers as Olivia. The total number of Raeann's and Olivia's wafers is 6 times of Kylie's. Raeann and Olivia have 80 wafers more than Kylie's. How many less wafers does Kylie have than Raeann?
| Raeann |
Olivia |
Kylie |
| 3x3 |
1x3 |
|
| 6x2 |
1x2 |
| 9 u |
3 u |
2 u |
The total number of wafers that Raeann and Olivia have is repeated. Make the total number of wafers that Raeann and Olivia have the same. LCM of 4 and 6 is 12.
Total number of wafers that Raeann and Olivia have
= 9 u + 3 u
= 12 u
Number of more wafers that Raeann and Olivia have than Kylie
= 12 u - 2 u
= 10 u
10 u = 80
1 u = 80 ÷ 10 = 8
Number of less wafers that Kylie has than Raeann
= 9 u - 2 u
= 7 u
= 7 x 8
= 56
Answer(s): 56
