Comparing Diana
and Xylia at first |
5x7 =
35 u |
1x7 =
7 u |
| Before |
7x5 =
35 u |

| Change |
- 5x5 =
- 25 u |
+ 5x5 =
+ 25 u |
| After |
2x5 =
10 u |
32 u |
20% =
20100 =
15The number of beads that Diana had at first is repeated. Make the number of beads that Diana had at first the same. LCM of 5 and 7 is 35.
Number of beads that Xylia had in the end
= 7 u + 25 u
= 32 u
Number of less beads that Diana had than Xylia in the end
= 32 u - 10 u
= 22 u
Number of less beads that Diana had than Xylia in the end in percent
=
2232 x 100%
≈ 68.8%
Answer(s): 68.8%
