Jade has 4 times as many muffins as Xuan. The total number of Jade's and Xuan's muffins is 2 times of Erika's. Jade and Xuan have 25 muffins more than Erika's. How many less muffins does Erika have than Jade?
| Jade |
Xuan |
Erika |
| 4x2 |
1x2 |
|
| 2x5 |
1x5 |
| 8 u |
2 u |
5 u |
The total number of muffins that Jade and Xuan have is repeated. Make the total number of muffins that Jade and Xuan have the same. LCM of 5 and 2 is 10.
Total number of muffins that Jade and Xuan have
= 8 u + 2 u
= 10 u
Number of more muffins that Jade and Xuan have than Erika
= 10 u - 5 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Number of less muffins that Erika has than Jade
= 8 u - 5 u
= 3 u
= 3 x 5
= 15
Answer(s): 15
