1 u |
The number of lollipops that Victoria had in the end is repeated. Make the number of lollipops that Victoria had in the end the same. LCM of 1 and 2 is 2.
Number of lollipops that Victoria had more than Xuan
= 8 u - 3 u
= 5 u
5 u = 45
1 u = 45 ÷ 5 = 9
Number of lollipops that Xuan had at first
= 3 u
= 3 x 9
= 27
Answer(s): 27
