Ivory has 2 times as many croissants as Roshel. The total number of Ivory's and Roshel's croissants is 6 times of Hilda's. Ivory and Roshel have 35 croissants more than Hilda's. How many less croissants does Hilda have than Ivory?
| Ivory |
Roshel |
Hilda |
| 2x2 |
1x2 |
|
| 6x1 |
1x1 |
| 4 u |
2 u |
1 u |
The total number of croissants that Ivory and Roshel have is repeated. Make the total number of croissants that Ivory and Roshel have the same. LCM of 3 and 6 is 6.
Total number of croissants that Ivory and Roshel have
= 4 u + 2 u
= 6 u
Number of more croissants that Ivory and Roshel have than Hilda
= 6 u - 1 u
= 5 u
5 u = 35
1 u = 35 ÷ 5 = 7
Number of less croissants that Hilda has than Ivory
= 4 u - 1 u
= 3 u
= 3 x 7
= 21
Answer(s): 21
