Comparing Fanny
and Kylie at first |
5x7 =
35 u |
2x7 =
14 u |
| Before |
7x5 =
35 u |

| Change |
- 5x5 =
- 25 u |
+ 5x5 =
+ 25 u |
| After |
2x5 =
10 u |
39 u |

25The number of beads that Fanny had at first is repeated. Make the number of beads that Fanny had at first the same. LCM of 5 and 7 is 35.
Number of beads that Kylie had in the end
= 14 u + 25 u
= 39 u
Number of less beads that Fanny had than Kylie in the end
= 39 u - 10 u
= 29 u
Number of less beads that Fanny had than Kylie in the end in percent
=
2939 x 100%
≈ 74.4%
Answer(s): 74.4%
