Emily and Emma shared some marbles. Emily had 60% of what Emma had at first. Emily then gave Emma
58 of what she had. How many more percent did Emma have than Emily in the end? Correct the answer to 1 decimal place.

Emma |
Comparing Emily and Emma at first |
5x8 = 40 u |
3x8 = 24 u |
Before |
8x5 = 40 u |
|
Change |
- 5x5 = - 25 u |
+ 5x5 = + 25 u |
After |
3x5 = 15 u |
49 u |
60% =
60100 =
35The number of marbles that Emily had at first is repeated. Make the number of marbles that Emily had at first the same. LCM of 5 and 8 is 40.
Number of marbles that Emma had in the end
= 24 u + 25 u
= 49 u
Number of more marbles that Emma had than Emily in the end
= 49 u - 15 u
= 34 u
Number of more marbles that Emma had than Emily in the end in percent
=
3415 x 100%
≈ 226.7%
Answer(s): 226.7%
