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

4 u |
1 u |
The number of lollipops that Roshel had in the end is repeated. Make the number of lollipops that Roshel had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Emma had less than Roshel
= 24 u - 4 u
= 20 u
20 u = 120
1 u = 120 ÷ 20 = 6
Number of lollipops that Roshel had at first
= 24 u
= 24 x 6
= 144
Answer(s): 144
