Ivory has 5 times as many muffins as Gillian. The total number of Ivory's and Gillian's muffins is 2 times of Sabrina's. Ivory and Gillian have 9 muffins more than Sabrina's. How many more muffins does Ivory have than Gillian?
| Ivory |
Gillian |
Sabrina |
| 5x1 |
1x1 |
|
| 2x3 |
1x3 |
| 5 u |
1 u |
3 u |
The total number of muffins that Ivory and Gillian have is repeated. Make the total number of muffins that Ivory and Gillian have the same. LCM of 6 and 2 is 6.
Total number of muffins that Ivory and Gillian have
= 5 u + 1 u
= 6 u
Number of more muffins that Ivory and Gillian have than Sabrina
= 6 u - 3 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of more muffins that Ivory has than Gillian
= 5 u - 1 u
= 4 u
= 4 x 3
= 12
Answer(s): 12
