Fractional Relations:
Let us understand this topic using the below example.
Here is the square with some lines
We need to find the fraction of a area of the whole square that is shaded.
Let the area of the whole square be \(1\) square unit.
From the figure we get, the top right square occupies \(\frac{1}{4}\) of the whole square.
Area of above top right square = \(\frac{1}{4}\) square units.
We can split the above square in this below way,
This yellow shade is detailed explanation of above figure.Area of yellow triangle \(= \frac{1}{2} \times \frac{1}{4} = \frac{1}{8} \text{square units}\)
The shaded region in the question occupies \(\frac{3}{4}\) space in yellow region
Thus the area of shaded region \(= \frac{3}{4} \times \frac{1}{8} = \frac{3}{32} \text{square units}\)
