- 5x4 = - 20 u |
- 2 u |
After |
1x4 = 4 u |

1 u |
The number of candy canes that Raeann had in the end is repeated. Make the number of candy canes that Raeann had in the end the same. LCM of 1 and 4 is 4.
Number of candy canes that Raeann had more than Rachel
= 24 u - 3 u
= 21 u
21 u = 189
1 u = 189 ÷ 21 = 9
Number of candy canes that Rachel had at first
= 3 u
= 3 x 9
= 27
Answer(s): 27
