The number of jelly beans that Fanny had in the end is repeated. Make the number of jelly beans that Fanny had in the end the same. LCM of 1 and 2 is 2.
Number of jelly beans that Joelle had less than Fanny
= 14 u - 3 u
= 11 u
11 u = 22
1 u = 22 ÷ 11 = 2
Number of jelly beans that Fanny had at first
= 14 u
= 14 x 2
= 28
Answer(s): 28
