1x2 =
2 u |
The number of stickers that Vanessa had at first and in the end remains unchanged. Make the number of stickers that Vanessa had the same. LCM of 8 and 4 is 8.
Number of stickers that Vanessa had more than Jean at first
= 8 u - 5 u
= 3 u
3 u = 102
1 u = 102 ÷ 3 = 34
Number of stickers that Jean had at first
= 5 u
= 5 x 34
= 170
Answer(s): 170
