Comparing Gem
and Xylia at first |
4x5 =
20 u |
3x5 =
15 u |
| Before |
5x4 =
20 u |
|
| Change |
- 2x4 =
- 8 u |
+ 2x4 =
+ 8 u |
| After |
3x4 =
12 u |
23 u |
75% =
75100 =
34The number of stamps that Gem had at first is repeated. Make the number of stamps that Gem had at first the same. LCM of 4 and 5 is 20.
Number of stamps that Xylia had in the end
= 15 u + 8 u
= 23 u
Number of more stamps that Xylia had than Gem in the end
= 23 u - 12 u
= 11 u
Number of more stamps that Xylia had than Gem in the end in percent
=
1112 x 100%
≈ 91.7%
Answer(s): 91.7%
