Sabrina has 4 times as many wafers as Hilda. The total number of Sabrina's and Hilda's wafers is 3 times of Gem's. Sabrina and Hilda have 60 wafers more than Gem's. How many more wafers does Sabrina have than Hilda?
| Sabrina |
Hilda |
Gem |
| 4x3 |
1x3 |
|
| 3x5 |
1x5 |
| 12 u |
3 u |
5 u |
The total number of wafers that Sabrina and Hilda have is repeated. Make the total number of wafers that Sabrina and Hilda have the same. LCM of 5 and 3 is 15.
Total number of wafers that Sabrina and Hilda have
= 12 u + 3 u
= 15 u
Number of more wafers that Sabrina and Hilda have than Gem
= 15 u - 5 u
= 10 u
10 u = 60
1 u = 60 ÷ 10 = 6
Number of more wafers that Sabrina has than Hilda
= 12 u - 3 u
= 9 u
= 9 x 6
= 54
Answer(s): 54
