It is 2/13. Divide number and denominator by 8.
Answer:
The value of the expression is 4.
Step-by-step explanation:
Consider the provided information.
We have given that:
![\dfrac{2\dfrac{1}{2} }{\dfrac{1}{8} } =20](https://tex.z-dn.net/?f=%5Cdfrac%7B2%5Cdfrac%7B1%7D%7B2%7D%20%7D%7B%5Cdfrac%7B1%7D%7B8%7D%20%7D%20%3D20)
Now we need to find the value of:
![\dfrac{2\dfrac{1}{2} }{\dfrac{5}{8} } =?](https://tex.z-dn.net/?f=%5Cdfrac%7B2%5Cdfrac%7B1%7D%7B2%7D%20%7D%7B%5Cdfrac%7B5%7D%7B8%7D%20%7D%20%3D%3F)
Consider the provided fact:
![\dfrac{2\dfrac{1}{2} }{\dfrac{1}{8} } =20](https://tex.z-dn.net/?f=%5Cdfrac%7B2%5Cdfrac%7B1%7D%7B2%7D%20%7D%7B%5Cdfrac%7B1%7D%7B8%7D%20%7D%20%3D20)
Multiply
both sides.
![\dfrac{1}{5}\times \dfrac{2\dfrac{1}{2} }{\dfrac{1}{8} } =20\times\dfrac{1}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B5%7D%5Ctimes%20%5Cdfrac%7B2%5Cdfrac%7B1%7D%7B2%7D%20%7D%7B%5Cdfrac%7B1%7D%7B8%7D%20%7D%20%3D20%5Ctimes%5Cdfrac%7B1%7D%7B5%7D)
![\dfrac{1\times2\dfrac{1}{2} }{5\times\dfrac{1}{8} } =20\times\dfrac{1}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%5Ctimes2%5Cdfrac%7B1%7D%7B2%7D%20%7D%7B5%5Ctimes%5Cdfrac%7B1%7D%7B8%7D%20%7D%20%3D20%5Ctimes%5Cdfrac%7B1%7D%7B5%7D)
![\dfrac{2\dfrac{1}{2} }{\dfrac{5}{8} } =4](https://tex.z-dn.net/?f=%5Cdfrac%7B2%5Cdfrac%7B1%7D%7B2%7D%20%7D%7B%5Cdfrac%7B5%7D%7B8%7D%20%7D%20%3D4)
Hence, the value of the expression is 4.

Diagonals of a parallelogram bisect each other
or they intersect each other in the halfway
x+4=3y-11-------------------------equation1
2x-1=y-1-------------------------------equation2
mulitply equation 1 to 2
2x+8=6y-22-----------------------equation3
equation2 - equation3
-9=-5y +21
5y=30
y=6
then x= 3
now PT=2x-1=5
TR=y-1=5
ST=3y-11=7
TQ=x+4=3+4=7
