The number of sweets that Pamela had in the end is repeated. Make the number of sweets that Pamela had in the end the same. LCM of 1 and 4 is 4.
Number of sweets that Pamela had more than Elyse
= 16 u - 2 u
= 14 u
14 u = 140
1 u = 140 ÷ 14 = 10
Number of sweets that Elyse had at first
= 2 u
= 2 x 10
= 20
Answer(s): 20
