Comparing Nicole
and Esther at first |
2x7 =
14 u |
1x7 =
7 u |
| Before |
7x2 =
14 u |
|
| Change |
- 2x2 =
- 4 u |
+ 2x2 =
+ 4 u |
| After |
5x2 =
10 u |
11 u |

12The number of beads that Nicole had at first is repeated. Make the number of beads that Nicole had at first the same. LCM of 2 and 7 is 14.
Number of beads that Esther had in the end
= 7 u + 4 u
= 11 u
Number of less beads that Nicole had than Esther in the end
= 11 u - 10 u
= 1 u
Number of less beads that Nicole had than Esther in the end in percent
=
111 x 100%
≈ 9.1%
Answer(s): 9.1%
