8/10 is the fraction can be read as 8 out of 10.
So, in order to represent it visually, we can make a circle first.
Then divide the circle 10 identical parts.
As given fraction is 8 out of 10, we need to shade 8 parts out of all 10 parts.
That shaded portion would represent fraction 8/10.
I have attached a diagram.
The circle is divided into 10 identical parts and I shaded 8 parts of it by red color.
That red colored shaded portion represents 8/10.

Answer:
x = -1 and y = 1/2
Step-by-step explanation:
Let u = 1/x, and v = 1/y
Then the pair of equations
-3/x + 4/y = 11
1/x - 2/y = -5
Can be written as
-3u + 4v = 11 .................................(1)
u - 2v = -5......................................(2)
From (2)
u = 2v - 5 .......................................(3)
Substituting (3) into (1)
-3(2v - 5) + 4v = 11
-6v + 15 + 4v = 11
-6v + 4v = 11 - 15
-2v = -4
v = 4/2 = 2
Substituting this value of v in (3)
u = 2v - 5
u = 2(2) - 5
= 4 - 5
= -1
That is
u = -1, v = 2
Since u = 1/x, and v = 1/y, we have
1/x = -1
=> x = -1
And
1/y = 2
=> y = 1/2
Therefore
x = -1 and y = 1/2
