The number of sweets that Lynn had in the end is repeated. Make the number of sweets that Lynn had in the end the same. LCM of 1 and 4 is 4.
Number of sweets that Kimberly had less than Lynn
= 16 u - 2 u
= 14 u
14 u = 42
1 u = 42 ÷ 14 = 3
Number of sweets that Lynn had at first
= 16 u
= 16 x 3
= 48
Answer(s): 48
