45 of what she had. How many less percent did Esther have than Anna in the end? Correct the answer to 1 decimal place.

Esther |
Anna |
Comparing Esther and Anna at first |
10x1 = 10 u |
1x1 = 1 u |
Before |
5x2 = 10 u |
|
Change |
- 4x2 = - 8 u |
+ 4x2 = + 8 u |
After |
1x2 = 2 u |
9 u |
10% =
10100 =
110The number of beads that Esther had at first is repeated. Make the number of beads that Esther had at first the same. LCM of 10 and 5 is 10.
Number of beads that Anna had in the end
= 1 u + 8 u
= 9 u
Number of less beads that Esther had than Anna in the end
= 9 u - 2 u
= 7 u
Number of less beads that Esther had than Anna in the end in percent
=
79 x 100%
≈ 77.8%
Answer(s): 77.8%
