- 4 u |
| After |
1x4 =

4 u |
1 u |
The number of lollipops that Eva had in the end is repeated. Make the number of lollipops that Eva had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Eva had more than Wendy
= 20 u - 5 u
= 15 u
15 u = 60
1 u = 60 ÷ 15 = 4
Number of lollipops that Wendy had at first
= 5 u
= 5 x 4
= 20
Answer(s): 20
