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 2 is 2.
Number of sweets that Opal had more than Tiffany
= 14 u - 4 u
= 10 u
10 u = 60
1 u = 60 ÷ 10 = 6
Number of sweets that Tiffany had at first
= 4 u
= 4 x 6
= 24
Answer(s): 24
