The number of chocolate bars that Kylie had in the end is repeated. Make the number of chocolate bars that Kylie had in the end the same. LCM of 1 and 3 is 3.
Number of chocolate bars that Hazel had less than Kylie
= 18 u - 4 u
= 14 u
14 u = 28
1 u = 28 ÷ 14 = 2
Number of chocolate bars that Kylie had at first
= 18 u
= 18 x 2
= 36
Answer(s): 36
