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