| After |
1x4 =

1 u |
The number of lollipops that Natalie had in the end is repeated. Make the number of lollipops that Natalie had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Yen had less than Natalie
= 20 u - 4 u
= 16 u
16 u = 160
1 u = 160 ÷ 16 = 10
Number of lollipops that Natalie had at first
= 20 u
= 20 x 10
= 200
Answer(s): 200
