The number of sweets that Tiffany had in the end is repeated. Make the number of sweets that Tiffany had in the end the same. LCM of 1 and 4 is 4.
Number of sweets that Tiffany had more than Gwen
= 16 u - 5 u
= 11 u
11 u = 55
1 u = 55 ÷ 11 = 5
Number of sweets that Gwen had at first
= 5 u
= 5 x 5
= 25
Answer(s): 25
