3 u |
1 u |
The number of lollipops that Abi had in the end is repeated. Make the number of lollipops that Abi had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Abi had more than Lynn
= 15 u - 5 u
= 10 u
10 u = 120
1 u = 120 ÷ 10 = 12
Number of lollipops that Lynn had at first
= 5 u
= 5 x 12
= 60
Answer(s): 60
