The number of sweets that Emma had in the end is repeated. Make the number of sweets that Emma had in the end the same. LCM of 1 and 2 is 2.
Number of sweets that Hilda had less than Emma
= 14 u - 2 u
= 12 u
12 u = 24
1 u = 24 ÷ 12 = 2
Number of sweets that Emma had at first
= 14 u
= 14 x 2
= 28
Answer(s): 28
