The number of lollipops that Kimberly had in the end is repeated. Make the number of lollipops that Kimberly had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Fanny had less than Kimberly
= 18 u - 3 u
= 15 u
15 u = 30
1 u = 30 ÷ 15 = 2
Number of lollipops that Kimberly had at first
= 18 u
= 18 x 2
= 36
Answer(s): 36
