Comparing Abi
and Raeann at first |
10x4 =
40 u |
3x4 =
12 u |
| Before |
8x5 =
40 u |
|
| Change |
- 5x5 =
- 25 u |
+ 5x5 =
+ 25 u |
| After |
3x5 =
15 u |
37 u |
30% =
30100 =
310The number of erasers that Abi had at first is repeated. Make the number of erasers that Abi had at first the same. LCM of 10 and 8 is 40.
Number of erasers that Raeann had in the end
= 12 u + 25 u
= 37 u
Number of more erasers that Raeann had than Abi in the end
= 37 u - 15 u
= 22 u
Number of more erasers that Raeann had than Abi in the end in percent
=
2215 x 100%
≈ 146.7%
Answer(s): 146.7%
