The number of chocolate bars that Esther had in the end is repeated. Make the number of chocolate bars that Esther had in the end the same. LCM of 1 and 4 is 4.
Number of chocolate bars that Jade had less than Esther
= 28 u - 4 u
= 24 u
24 u = 288
1 u = 288 ÷ 24 = 12
Number of chocolate bars that Esther had at first
= 28 u
= 28 x 12
= 336
Answer(s): 336
