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