Comparing Jen
and Erika at first |
10x4 =
40 u |
3x4 =
12 u |
| Before |
8x5 =
40 u |

| Change |
- 3x5 =
- 15 u |
+ 3x5 =
+ 15 u |
| After |
5x5 =
25 u |
27 u |

310The number of beads that Jen had at first is repeated. Make the number of beads that Jen had at first the same. LCM of 10 and 8 is 40.
Number of beads that Erika had in the end
= 12 u + 15 u
= 27 u
Number of less beads that Jen had than Erika in the end
= 27 u - 25 u
= 2 u
Number of less beads that Jen had than Erika in the end in percent
=
227 x 100%
≈ 7.4%
Answer(s): 7.4%
