Min has 6 times as many biscuits as Wendy. The total number of Min's and Wendy's biscuits is 4 times of Olivia's. Min and Wendy have 189 biscuits more than Olivia's. How many more biscuits does Min have than Wendy?
| Min |
Wendy |
Olivia |
| 6x4 |
1x4 |
|
| 4x7 |
1x7 |
| 24 u |
4 u |
7 u |
The total number of biscuits that Min and Wendy have is repeated. Make the total number of biscuits that Min and Wendy have the same. LCM of 7 and 4 is 28.
Total number of biscuits that Min and Wendy have
= 24 u + 4 u
= 28 u
Number of more biscuits that Min and Wendy have than Olivia
= 28 u - 7 u
= 21 u
21 u = 189
1 u = 189 ÷ 21 = 9
Number of more biscuits that Min has than Wendy
= 24 u - 4 u
= 20 u
= 20 x 9
= 180
Answer(s): 180
