Comparing Jaslyn
and Usha at first |
10x4 =
40 u |
1x4 =
4 u |
| Before |
8x5 =
40 u |
|
| Change |
- 5x5 =
- 25 u |
+ 5x5 =
+ 25 u |
| After |
3x5 =
15 u |
29 u |
10% =
10100 =
110The number of pens that Jaslyn had at first is repeated. Make the number of pens that Jaslyn had at first the same. LCM of 10 and 8 is 40.
Number of pens that Usha had in the end
= 4 u + 25 u
= 29 u
Number of less pens that Jaslyn had than Usha in the end
= 29 u - 15 u
= 14 u
Number of less pens that Jaslyn had than Usha in the end in percent
=
1429 x 100%
≈ 48.3%
Answer(s): 48.3%
