1 u |
The number of lollipops that Hilda had in the end is repeated. Make the number of lollipops that Hilda had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Emma had less than Hilda
= 28 u - 4 u
= 24 u
24 u = 120
1 u = 120 ÷ 24 = 5
Number of lollipops that Hilda had at first
= 28 u
= 28 x 5
= 140
Answer(s): 140
