Comparing Pamela
and Fanny at first |
10x7 =
70 u |
7x7 =
49 u |
| Before |
7x10 =
70 u |
|
| Change |
- 4x10 =
- 40 u |
+ 4x10 =
+ 40 u |
| After |
3x10 =
30 u |
89 u |
70% =
70100 =
710The number of coins that Pamela had at first is repeated. Make the number of coins that Pamela had at first the same. LCM of 10 and 7 is 70.
Number of coins that Fanny had in the end
= 49 u + 40 u
= 89 u
Number of more coins that Fanny had than Pamela in the end
= 89 u - 30 u
= 59 u
Number of more coins that Fanny had than Pamela in the end in percent
=
5930 x 100%
≈ 196.7%
Answer(s): 196.7%
