The number of candy canes that Joelle had in the end is repeated. Make the number of candy canes that Joelle had in the end the same. LCM of 1 and 2 is 2.
Number of candy canes that Sabrina had less than Joelle
= 14 u - 4 u
= 10 u
10 u = 40
1 u = 40 ÷ 10 = 4
Number of candy canes that Joelle had at first
= 14 u
= 14 x 4
= 56
