Comparing Xandra
and Fanny at first |
4x5 =
20 u |
3x5 =
15 u |
| Before |
5x4 =
20 u |

| Change |
- 3x4 =
- 12 u |
+ 3x4 =
+ 12 u |
| After |
2x4 =
8 u |
27 u |
75% =

34The number of buttons that Xandra had at first is repeated. Make the number of buttons that Xandra had at first the same. LCM of 4 and 5 is 20.
Number of buttons that Fanny had in the end
= 15 u + 12 u
= 27 u
Number of less buttons that Xandra had than Fanny in the end
= 27 u - 8 u
= 19 u
Number of less buttons that Xandra had than Fanny in the end in percent
=
1927 x 100%
≈ 70.4%
Answer(s): 70.4%
