Comparing Anna
and Ivory at first |
5x8 =
40 u |
2x8 =
16 u |
| Before |
8x5 =
40 u |
|
| Change |
- 3x5 =
- 15 u |
+ 3x5 =
+ 15 u |
| After |
5x5 =
25 u |
31 u |
40% =
40100 =
25The number of stamps that Anna had at first is repeated. Make the number of stamps that Anna had at first the same. LCM of 5 and 8 is 40.
Number of stamps that Ivory had in the end
= 16 u + 15 u
= 31 u
Number of less stamps that Anna had than Ivory in the end
= 31 u - 25 u
= 6 u
Number of less stamps that Anna had than Ivory in the end in percent
=
631 x 100%
≈ 19.4%
Answer(s): 19.4%
