The number of chocolate bars that Jen had in the end is repeated. Make the number of chocolate bars that Jen had in the end the same. LCM of 1 and 2 is 2.
Number of chocolate bars that Jen had more than Lynn
= 8 u - 4 u
= 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Number of chocolate bars that Lynn had at first
= 4 u
= 4 x 4
= 16
Answer(s): 16
