The number of chocolate bars that Joelle had in the end is repeated. Make the number of chocolate bars that Joelle had in the end the same. LCM of 1 and 4 is 4.
Number of chocolate bars that Joelle had more than Jaslyn
= 20 u - 4 u
= 16 u
16 u = 64
1 u = 64 ÷ 16 = 4
Number of chocolate bars that Jaslyn had at first
= 4 u
= 4 x 4
= 16
Answer(s): 16
