Comparing Hazel
and Gwen at first |
5x7 =
35 u |
3x7 =
21 u |
| Before |
7x5 =
35 u |

| Change |
- 4x5 =
- 20 u |
+ 4x5 =
+ 20 u |
| After |
3x5 =
15 u |
41 u |
60% =

35The number of marbles that Hazel had at first is repeated. Make the number of marbles that Hazel had at first the same. LCM of 5 and 7 is 35.
Number of marbles that Gwen had in the end
= 21 u + 20 u
= 41 u
Number of more marbles that Gwen had than Hazel in the end
= 41 u - 15 u
= 26 u
Number of more marbles that Gwen had than Hazel in the end in percent
=
2615 x 100%
≈ 173.3%
Answer(s): 173.3%
