Emily has 6 times as many wafers as Min. The total number of Emily's and Min's wafers is 4 times of Olivia's. Emily and Min have 63 wafers more than Olivia's. How many more wafers does Emily have than Min?
| Emily |
Min |
Olivia |
| 6x4 |
1x4 |
|
| 4x7 |
1x7 |
| 24 u |
4 u |
7 u |
The total number of wafers that Emily and Min have is repeated. Make the total number of wafers that Emily and Min have the same. LCM of 7 and 4 is 28.
Total number of wafers that Emily and Min have
= 24 u + 4 u
= 28 u
Number of more wafers that Emily and Min have than Olivia
= 28 u - 7 u
= 21 u
21 u = 63
1 u = 63 ÷ 21 = 3
Number of more wafers that Emily has than Min
= 24 u - 4 u
= 20 u
= 20 x 3
= 60
Answer(s): 60
