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.
