Comparing Fiona
and Gwen at first |
4x5 =
20 u |
3x5 =
15 u |
| Before |
5x4 =
20 u |
|
| Change |
- 2x4 =
- 8 u |
+ 2x4 =
+ 8 u |
| After |
3x4 =
12 u |
23 u |
75% =

34The number of beads that Fiona had at first is repeated. Make the number of beads that Fiona had at first the same. LCM of 4 and 5 is 20.
Number of beads that Gwen had in the end
= 15 u + 8 u
= 23 u
Number of more beads that Gwen had than Fiona in the end
= 23 u - 12 u
= 11 u
Number of more beads that Gwen had than Fiona in the end in percent
=
1112 x 100%
≈ 91.7%
Answer(s): 91.7%
