Given:
Point P is Nine-elevenths of the distance from M to N.
To find:
The ratio in which point P partition the directed line segment from M to N.
Solution:
It is given that, point P is Nine-elevenths of the distance from M to N. So,
![(MP)/(MN)=(9)/(11)](https://img.qammunity.org/2022/formulas/mathematics/high-school/r6jhewucxrs0pi4qekq7y5t4ojmmad7d7q.png)
It can be written as
![(MP)/(MN)=(9)/(11)](https://img.qammunity.org/2022/formulas/mathematics/high-school/r6jhewucxrs0pi4qekq7y5t4ojmmad7d7q.png)
Let the lengths of MP and MN are 9x and 11x respectively. Then,
![PN=MN-MP](https://img.qammunity.org/2022/formulas/mathematics/high-school/stts8jzpixovcz81hwhm50w6wx2trrqerq.png)
![PN=11x-9x](https://img.qammunity.org/2022/formulas/mathematics/high-school/t6mzdil3u8tf0pgnjy581san5s5um9et8c.png)
![PN=2x](https://img.qammunity.org/2022/formulas/mathematics/high-school/s8gcj2uibc7l1mkd0hbuc1agx7uq34qp09.png)
Now,
![(MP)/(PN)=(9x)/(2x)](https://img.qammunity.org/2022/formulas/mathematics/high-school/f6x86tu2hqdeaicn5dcmou8bwvf8gkmibn.png)
![(MP)/(PN)=(9)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/711pyq6g56hzbkq9da6hlnqvfcjblw5am2.png)
![(MP)/(PN)=9:2](https://img.qammunity.org/2022/formulas/mathematics/high-school/c7sjoe5q8d6ie1bx8h9hs8eheaxluc85uu.png)
It means, point P divides the line segment MN in 9:2.
Therefore, the correct option is A.
