Comparing Jean
and Cindy at first |
5x7 =
35 u |
2x7 =
14 u |
| Before |
7x5 =
35 u |

| Change |
- 4x5 =
- 20 u |
+ 4x5 =
+ 20 u |
| After |
3x5 =
15 u |
34 u |
40% =
40100 =
25The number of beads that Jean had at first is repeated. Make the number of beads that Jean had at first the same. LCM of 5 and 7 is 35.
Number of beads that Cindy had in the end
= 14 u + 20 u
= 34 u
Number of less beads that Jean had than Cindy in the end
= 34 u - 15 u
= 19 u
Number of less beads that Jean had than Cindy in the end in percent
=
1934 x 100%
≈ 55.9%
Answer(s): 55.9%
