The number of candy canes that Yoko had in the end is repeated. Make the number of candy canes that Yoko had in the end the same. LCM of 1 and 2 is 2.
Number of candy canes that Yoko had more than Dana
= 14 u - 3 u
= 11 u
11 u = 132
1 u = 132 ÷ 11 = 12
Number of candy canes that Dana had at first
= 3 u
= 3 x 12
= 36
Answer(s): 36
