1x2 =
2 u |
The number of stickers that Zoe had at first and in the end remains unchanged. Make the number of stickers that Zoe had the same. LCM of 8 and 4 is 8.
Number of stickers that Zoe had more than Fanny at first
= 8 u - 5 u
= 3 u
3 u = 150
1 u = 150 ÷ 3 = 50
Number of stickers that Fanny had at first
= 5 u
= 5 x 50
= 250
Answer(s): 250
