The number of sweets that Gwen had in the end is repeated. Make the number of sweets that Gwen had in the end the same. LCM of 1 and 4 is 4.
Number of sweets that Gwen had more than Roshel
= 32 u - 4 u
= 28 u
28 u = 336
1 u = 336 ÷ 28 = 12
Number of sweets that Roshel had at first
= 4 u
= 4 x 12
= 48
Answer(s): 48
