The number of chocolate bars that Linda had in the end is repeated. Make the number of chocolate bars that Linda had in the end the same. LCM of 1 and 2 is 2.
Number of chocolate bars that Fiona had less than Linda
= 16 u - 4 u
= 12 u
12 u = 24
1 u = 24 ÷ 12 = 2
Number of chocolate bars that Linda had at first
= 16 u
= 16 x 2
= 32
Answer(s): 32
