The number of candy canes that Gabby had in the end is repeated. Make the number of candy canes that Gabby had in the end the same. LCM of 1 and 3 is 3.
Number of candy canes that Gabby had more than Raeann
= 21 u - 3 u
= 18 u
18 u = 144
1 u = 144 ÷ 18 = 8
Number of candy canes that Raeann had at first
= 3 u
= 3 x 8
= 24
