The number of sweets that Jaslyn had in the end is repeated. Make the number of sweets that Jaslyn had in the end the same. LCM of 1 and 3 is 3.
Number of sweets that Cathy had less than Jaslyn
= 12 u - 4 u
= 8 u
8 u = 56
1 u = 56 ÷ 8 = 7
Number of sweets that Jaslyn had at first
= 12 u
= 12 x 7
= 84
Answer(s): 84
