The number of candy canes that Olivia had in the end is repeated. Make the number of candy canes that Olivia had in the end the same. LCM of 1 and 4 is 4.
Number of candy canes that Olivia had more than Xuan
= 24 u - 3 u
= 21 u
21 u = 210
1 u = 210 ÷ 21 = 10
Number of candy canes that Xuan had at first
= 3 u
= 3 x 10
= 30
Answer(s): 30
