The number of lollipops that Sabrina had in the end is repeated. Make the number of lollipops that Sabrina had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Sabrina had more than Jean
= 15 u - 3 u
= 12 u
12 u = 60
1 u = 60 ÷ 12 = 5
Number of lollipops that Jean had at first
= 3 u
= 3 x 5
= 15
Answer(s): 15
