Explanation
The given figure has $$3$$ large squares with $$4$$ parts in each square.
In the first square, all $$\dfrac4 4$$ parts are colored.
In the second square also all $$\dfrac4 4$$ parts are colored. In the third square, only $$\dfrac1 4$$ is colored.
So we can say that the given figures are $$1+1+\dfrac 1 4= 2$$ whole $$\dfrac1 4$$

Explanation
There are $$12$$ total squares in the given figure.
In order for it to be shaded $$\dfrac{1}{3}$$ of the figure total of $$4$$ squares have to be shaded.
In the given figure only 3 squares are shaded.
In order for it to be shaded $$\dfrac{1}{3}$$, we need to shade $$1$$ more box.
So option A is the correct answer.

Explanation
The triangle is divided into 4 parts, out of which only 1 part is shaded. We can also say, 1/4 of the triangle is shaded.
The circle is also divided in 4 parts out of which only 1 part is shaded. We can also say, 1/4 of the circle is shaded.
So we can also write the given figure as,
(1/4)+(1/4)=2/4
On simplification,
2/4=1/2.
So option A is the correct answer.

Explanation
The whole circle is divided in 8 parts.
Number of parts shaded is 2 parts.
So we can say 2 out of 8 parts is shaded.
This can be written in fraction form as 2/8
So option B is the correct answer.

$$0.5$$
Explanation
In total, there are $$12$$ blocks out of which $$6$$ of them are shaded and the rest $$6$$ are empty.
So,
$$\text{Fraction} = \dfrac{\text{shaded portion}}{\text{unshaded portion}}$$
$$ = \dfrac{6}{12}$$
$$= \dfrac{1}{2}$$
$$=0.5$$
Hence, Option D is the right answer.

0%
Explanation
For op-(A)
Total number of equal parts$$=4$$
Number of shaded parts $$= 2$$
Fraction of shaded portion $$=\dfrac{2}{4}=\dfrac{1}{2}$$
For op-(B)
Total number of equal parts$$=3$$
Number of shaded parts $$= 2$$
Fraction of shaded portion $$=\dfrac{2}{3}$$
For op-(C)
Total number of equal parts$$=4$$
Number of shaded parts $$= 3$$
Fraction of shaded portion $$=\dfrac{3}{4}$$
For op-(D)
Total number of equal parts$$=6$$
Number of shaded parts $$= 4$$
Fraction of shaded portion $$=\dfrac{4}{6}=\dfrac{2}{3}$$
Hence, $$Op-A$$ is correct.

Explanation
Let us assume
side of larger Square $$=4$$ units
It is divided into $$16$$ small squares of side $$1$$ unit each
Base of shaded Triangle $$=\sqrt{2}$$ units $$=$$ diagonal of square of $$1$$ unit side
Height of shaded Triangle $$=\sqrt{2}+\dfrac{\sqrt{2}}{2}$$ units
Area of 4 shaded triangles $$=4 \times \dfrac{1}{2}\times \sqrt{2}\times (\sqrt{2}+\dfrac{\sqrt{2}}{2}) = 6$$
$$\text{unit}^{2}$$
Area of Larger Square $$=$$ Total Area
Total Area $$= 4^{2} = 16$$ $$\text{unit}^{2}$$
Fraction of the figure is shaded $$= \dfrac{6}{16}$$

$$1\dfrac {3}{5}, 1.6, 3\dfrac {1}{2}, 3.5$$
Explanation
Shaded fraction of first figure is $$P = 1 + \dfrac {6}{10}$$
$$ = \dfrac {16}{10} = \dfrac {8}{5}$$
$$ = 1\dfrac {3}{5}$$
In decimal form, $$Q = 1.6$$
Shaded fraction of second figure $$R = 1 + 1 + 1 + \dfrac {5}{10}$$
$$= 3 + \dfrac {1}{2} = \dfrac {7}{2}$$
$$ = 3\dfrac {1}{2}$$
In decimal form, $$S = 3.5$$.

Explanation
Total parts in each square $$=9$$
Shaded parts in first $$=5$$
Fraction of shaded part $$=\dfrac{5}{9}$$
Shaded part in second $$=6$$
Fraction of shaded part $$=\dfrac{6}{9}$$
Total shaded part $$=\dfrac{5}{9}+\dfrac{6}{9}=1\dfrac{2}{9}$$

Explanation
For model-1,
Total number of equal parts =12
Number of shaded parts =9
Therefore shaded fraction =P=$$\dfrac{9}{12}$$=$$\dfrac{3}{4}$$
For model-2,
Total number of equal parts =6
Number of shaded parts = 3
Shaded fraction = Q= $$\dfrac{3}{6}$$=$$\dfrac{1\times 2}{2\times2}$$=$$\dfrac{2}{4}$$
Now, $$\dfrac{3}{4}$$>$$\dfrac{2}{4}$$
