Comparing Sabrina
and Elyse at first |
2x7 =
14 u |
1x7 =
7 u |
| Before |
7x2 =
14 u |
|
| Change |
- 3x2 =
- 6 u |
+ 3x2 =
+ 6 u |
| After |
4x2 =
8 u |
13 u |

12The number of beads that Sabrina had at first is repeated. Make the number of beads that Sabrina had at first the same. LCM of 2 and 7 is 14.
Number of beads that Elyse had in the end
= 7 u + 6 u
= 13 u
Number of less beads that Sabrina had than Elyse in the end
= 13 u - 8 u
= 5 u
Number of less beads that Sabrina had than Elyse in the end in percent
=
513 x 100%
≈ 38.5%
Answer(s): 38.5%
