Comparing Lynn

10x1 =
10 u |
1x1 =
1 u |
| Before |
5x2 =
10 u |

| Change |
- 4x2 =
- 8 u |
+ 4x2 =
+ 8 u |
| After |
1x2 =

110The number of beads that Lynn had at first is repeated. Make the number of beads that Lynn had at first the same. LCM of 10 and 5 is 10.
Number of beads that Fiona had in the end
= 1 u + 8 u
= 9 u
Number of less beads that Lynn had than Fiona in the end
= 9 u - 2 u
= 7 u
Number of less beads that Lynn had than Fiona in the end in percent
=
79 x 100%
≈ 77.8%
Answer(s): 77.8%
