The number of sweets that Nora had in the end is repeated. Make the number of sweets that Nora had in the end the same. LCM of 1 and 4 is 4.
Number of sweets that Nora had more than Olivia
= 16 u - 4 u
= 12 u
12 u = 108
1 u = 108 ÷ 12 = 9
Number of sweets that Olivia had at first
= 4 u
= 4 x 9
= 36
Answer(s): 36
