1 u |
The number of lollipops that Betty had in the end is repeated. Make the number of lollipops that Betty had in the end the same. LCM of 1 and 2 is 2.
Number of lollipops that Betty had more than Natalie
= 12 u - 4 u
= 8 u
8 u = 48
1 u = 48 ÷ 8 = 6
Number of lollipops that Natalie had at first
= 4 u
= 4 x 6
= 24
Answer(s): 24
