Jen and Jean shared some marbles. Jen had 25% of what Jean had at first. Jen then gave Jean
45 of what she had. How many less percent did Jen have than Jean in the end? Correct the answer to 1 decimal place.

Jen |
Jean |
Comparing Jen and Jean at first |
4x5 = 20 u |
1x5 = 5 u |
Before |
5x4 = 20 u |
|
Change |
- 4x4 = - 16 u |
+ 4x4 = + 16 u |
After |
1x4 = 4 u |
21 u |
25% =
25100 =
14The number of marbles that Jen had at first is repeated. Make the number of marbles that Jen had at first the same. LCM of 4 and 5 is 20.
Number of marbles that Jean had in the end
= 5 u + 16 u
= 21 u
Number of less marbles that Jen had than Jean in the end
= 21 u - 4 u
= 17 u
Number of less marbles that Jen had than Jean in the end in percent
=
1721 x 100%
≈ 81%
Answer(s): 81%
