The number of candy canes that Barbara had in the end is repeated. Make the number of candy canes that Barbara had in the end the same. LCM of 1 and 3 is 3.
Number of candy canes that Yoko had less than Barbara
= 18 u - 4 u
= 14 u
14 u = 70
1 u = 70 ÷ 14 = 5
Number of candy canes that Barbara had at first
= 18 u
= 18 x 5
= 90
Answer(s): 90
