Comparing Risa
and Julie at first |
10x4 =
40 u |
1x4 =
4 u |
| Before |
8x5 =
40 u |
|
| Change |
- 5x5 =
- 25 u |
+ 5x5 =
+ 25 u |
| After |
3x5 =
15 u |
29 u |
10% =
10100 =
110The number of coins that Risa had at first is repeated. Make the number of coins that Risa had at first the same. LCM of 10 and 8 is 40.
Number of coins that Julie had in the end
= 4 u + 25 u
= 29 u
Number of more coins that Julie had than Risa in the end
= 29 u - 15 u
= 14 u
Number of more coins that Julie had than Risa in the end in percent
=
1415 x 100%
≈ 93.3%
Answer(s): 93.3%
