Jane and Nicole shared some buttons. Jane had 75% of what Nicole had at first. Jane then gave Nicole
45 of what she had. How many less percent did Jane have than Nicole in the end? Correct the answer to 1 decimal place.

Jane |
Nicole |
Comparing Jane and Nicole at first |
4x5 = 20 u |
3x5 = 15 u |
Before |
5x4 = 20 u |
|
Change |
- 4x4 = - 16 u |
+ 4x4 = + 16 u |
After |
1x4 = 4 u |
31 u |
75% =
75100 =
34The number of buttons that Jane had at first is repeated. Make the number of buttons that Jane had at first the same. LCM of 4 and 5 is 20.
Number of buttons that Nicole had in the end
= 15 u + 16 u
= 31 u
Number of less buttons that Jane had than Nicole in the end
= 31 u - 4 u
= 27 u
Number of less buttons that Jane had than Nicole in the end in percent
=
2731 x 100%
≈ 87.1%
Answer(s): 87.1%
