The number of candy canes that Esther had in the end is repeated. Make the number of candy canes that Esther had in the end the same. LCM of 1 and 4 is 4.
Number of candy canes that Esther had more than Kathy
= 28 u - 5 u
= 23 u
23 u = 92
1 u = 92 ÷ 23 = 4
Number of candy canes that Kathy had at first
= 5 u
= 5 x 4
= 20
Answer(s): 20
