The number of sweets that Opal had in the end is repeated. Make the number of sweets that Opal had in the end the same. LCM of 1 and 4 is 4.
Number of sweets that Opal had more than Fanny
= 28 u - 3 u
= 25 u
25 u = 50
1 u = 50 ÷ 25 = 2
Number of sweets that Fanny had at first
= 3 u
= 3 x 2
= 6
Answer(s): 6
