Comparing Xylia
and Kathy at first |
5x8 =
40 u |
3x8 =
24 u |
| Before |
8x5 =
40 u |

| Change |
- 7x5 =
- 35 u |
+ 7x5 =
+ 35 u |
| After |
1x5 =
5 u |
59 u |

35The number of beads that Xylia had at first is repeated. Make the number of beads that Xylia had at first the same. LCM of 5 and 8 is 40.
Number of beads that Kathy had in the end
= 24 u + 35 u
= 59 u
Number of less beads that Xylia had than Kathy in the end
= 59 u - 5 u
= 54 u
Number of less beads that Xylia had than Kathy in the end in percent
=
5459 x 100%
≈ 91.5%
Answer(s): 91.5%
