The number of candy canes that Xuan had in the end is repeated. Make the number of candy canes that Xuan had in the end the same. LCM of 1 and 2 is 2.
Number of candy canes that Xuan had more than Gabby
= 14 u - 5 u
= 9 u
9 u = 90
1 u = 90 ÷ 9 = 10
Number of candy canes that Gabby had at first
= 5 u
= 5 x 10
= 50
Answer(s): 50
