The number of erasers that Joelle had at first and in the end remains unchanged. Make the number of erasers that Joelle had the same. LCM of 6 and 2 is 6.
Number of erasers that Joelle had more than Hilda at first
= 6 u - 4 u
= 2 u
2 u = 96
1 u = 96 ÷ 2 = 48
Number of erasers that Hilda had at first
= 4 u
= 4 x 48
= 192
Answer(s): 192
