Comparing Ivory
and Rachel at first |
5x8 =
40 u |
2x8 =
16 u |
| Before |
8x5 =
40 u |
|
| Change |
- 5x5 =
- 25 u |
+ 5x5 =
+ 25 u |
| After |
3x5 =
15 u |
41 u |
40% =
40100 =
25The number of pens that Ivory had at first is repeated. Make the number of pens that Ivory had at first the same. LCM of 5 and 8 is 40.
Number of pens that Rachel had in the end
= 16 u + 25 u
= 41 u
Number of less pens that Ivory had than Rachel in the end
= 41 u - 15 u
= 26 u
Number of less pens that Ivory had than Rachel in the end in percent
=
2641 x 100%
≈ 63.4%
Answer(s): 63.4%
