Comparing Tiffany
and Eva at first |
5x7 =
35 u |
2x7 =
14 u |
| Before |
7x5 =
35 u |
|
| Change |
- 4x5 =
- 20 u |
+ 4x5 =
+ 20 u |
| After |
3x5 =
15 u |
34 u |
40% =
40100 =
25The number of coins that Tiffany had at first is repeated. Make the number of coins that Tiffany had at first the same. LCM of 5 and 7 is 35.
Number of coins that Eva had in the end
= 14 u + 20 u
= 34 u
Number of more coins that Eva had than Tiffany in the end
= 34 u - 15 u
= 19 u
Number of more coins that Eva had than Tiffany in the end in percent
=
1915 x 100%
≈ 126.7%
Answer(s): 126.7%
