7x1 =
7 u |
| Before |
5x2 =
10 u |

| Change |
- 2x2 =
- 4 u |
+ 2x2 =
+ 4 u |
| After |
3x2 =

710The number of buttons that Elyse had at first is repeated. Make the number of buttons that Elyse had at first the same. LCM of 10 and 5 is 10.
Number of buttons that Wendy had in the end
= 7 u + 4 u
= 11 u
Number of more buttons that Wendy had than Elyse in the end
= 11 u - 6 u
= 5 u
Number of more buttons that Wendy had than Elyse in the end in percent
=
56 x 100%
≈ 83.3%
Answer(s): 83.3%
