1 u |
The number of lollipops that Kathy had in the end is repeated. Make the number of lollipops that Kathy had in the end the same. LCM of 1 and 2 is 2.
Number of lollipops that Abi had less than Kathy
= 8 u - 5 u
= 3 u
3 u = 33
1 u = 33 ÷ 3 = 11
Number of lollipops that Kathy had at first
= 8 u
= 8 x 11
= 88
Answer(s): 88
