The number of lollipops that Cindy had in the end is repeated. Make the number of lollipops that Cindy had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Cindy had more than Kathy
= 20 u - 4 u
= 16 u
16 u = 128
1 u = 128 ÷ 16 = 8
Number of lollipops that Kathy had at first
= 4 u
= 4 x 8
= 32
Answer(s): 32
