Shannon and Anna shared some beads. Shannon had 50% of what Anna had at first. Shannon then gave Anna
38 of what she had. How many less percent did Shannon have than Anna in the end? Correct the answer to 1 decimal place.

Comparing Shannon
and Anna at first |
2x4 =
8 u |
1x4 =
4 u |
| Before |
8x1 =
8 u |
|
| Change |
- 3x1 =
- 3 u |
+ 3x1 =
+ 3 u |
| After |
5x1 =
5 u |
7 u |
50% =
50100 =
12The number of beads that Shannon had at first is repeated. Make the number of beads that Shannon had at first the same. LCM of 2 and 8 is 8.
Number of beads that Anna had in the end
= 4 u + 3 u
= 7 u
Number of less beads that Shannon had than Anna in the end
= 7 u - 5 u
= 2 u
Number of less beads that Shannon had than Anna in the end in percent
=
27 x 100%
≈ 28.6%
Answer(s): 28.6%
