Comparing Jaslyn and Kylie at first |
4x7 = 28 u |
1x7 = 7 u |
Before |
7x4 = 28 u |
|
Change |
- 4x4 = - 16 u |
+ 4x4 = + 16 u |
After |
3x4 = 12 u |
23 u |
25% =
25100 =
14The number of pens that Jaslyn had at first is repeated. Make the number of pens that Jaslyn had at first the same. LCM of 4 and 7 is 28.
Number of pens that Kylie had in the end
= 7 u + 16 u
= 23 u
Number of more pens that Kylie had than Jaslyn in the end
= 23 u - 12 u
= 11 u
Number of more pens that Kylie had than Jaslyn in the end in percent
=
1112 x 100%
≈ 91.7%
Answer(s): 91.7%
