Comparing Risa
and Raeann at first |
5x8 =
40 u |
3x8 =
24 u |
| Before |
8x5 =
40 u |
|
| Change |
- 3x5 =
- 15 u |
+ 3x5 =
+ 15 u |
| After |
5x5 =
25 u |
39 u |
60% =
60100 =
35The number of cards that Risa had at first is repeated. Make the number of cards that Risa had at first the same. LCM of 5 and 8 is 40.
Number of cards that Raeann had in the end
= 24 u + 15 u
= 39 u
Number of less cards that Risa had than Raeann in the end
= 39 u - 25 u
= 14 u
Number of less cards that Risa had than Raeann in the end in percent
=
1439 x 100%
≈ 35.9%
Answer(s): 35.9%
