Comparing Ivory
and Abi at first |
10x4 =
40 u |
7x4 =
28 u |
| Before |
8x5 =
40 u |
|
| Change |
- 7x5 =
- 35 u |
+ 7x5 =
+ 35 u |
| After |
1x5 =
5 u |
63 u |
70% =
70100 =
710The number of cards that Ivory had at first is repeated. Make the number of cards that Ivory had at first the same. LCM of 10 and 8 is 40.
Number of cards that Abi had in the end
= 28 u + 35 u
= 63 u
Number of less cards that Ivory had than Abi in the end
= 63 u - 5 u
= 58 u
Number of less cards that Ivory had than Abi in the end in percent
=
5863 x 100%
≈ 92.1%
Answer(s): 92.1%
