Explanation
Out of three 2 are completely shaded and one is half shaded so total shahded area will be $$2+\frac{1}{2}$$
=$$2\frac{1}{2}$$
So correct answer is option C

0%
$$\displaystyle \frac {2}{7}\, +\, \displaystyle \frac {1}{7}\, +\, \displaystyle \frac {2}{7}\, =\, \displaystyle \frac {5}{7}$$
Explanation
Shaded part with checks is $$2$$ parts out of $$7$$ parts
Shaded part with oblique lines from top right to bottom left is $$2$$ parts out of $$7$$ parts
Shaded part with vertical lines is $$1$$ part out of $$7$$ parts
Hence, fraction of the shaded region to unshaded part is $$\displaystyle \frac { 2 }{ 7 } +\frac { 1 }{ 7 } +\frac { 2 }{ 7 } =\frac { 5 }{ 7 } $$

Explanation
The fractional part of the pizza left = $$1-(\displaystyle{\frac{1}{8}}+\dfrac{1}{2})$$
$$=1-(\cfrac{1}{8}+\dfrac{4}{8})$$
$$=1-\cfrac{5}{8}$$
$$=\cfrac{8}{8}-\dfrac{5}{8}$$
$$=\cfrac{3}{8}$$
$$\therefore$$ $$\dfrac{3}{8}$$ represents option $$A$$.

Explanation
Consider one large square to be $$1$$ unit.
Then from the figure, two squares are fully painted.
Third square is $$ \displaystyle \frac {1}{4}th$$ painted.
$$\therefore $$ The fraction that the squares are shaded is given by
$$2\displaystyle \frac { 1 }{ 4 } $$
In which figure does the shaded part represent $$\displaystyle{\frac{1}{3}}$$ ?

Explanation
In the figure of option $$B$$ figure is divided in to $$3$$ equal parts in which one part is shaded . So this shaded part in option $$B$$ is $$\dfrac{1}{3}$$ of the whole shape. Hence option $$B$$ is answer.

Explanation
In the first image, there are $$4$$ parts and the ratio of the area of shaded part with the whole area is $$1:4$$
In second image, there are $$8$$ parts and the ratio of area of shaded part with compare to the whole area is $$3:8$$
Similarly, the third figure has the ratio of $$3:5$$
But in the fourth image, there are two parts, one shaded and another unshaded.
So, the ratio of the area of the shaded part with the whole area will be $$1:2$$ which is equivalent to $$3:6$$.
Hence, option D is correct.

$$\displaystyle \frac {8} {20} $$
0%
$$\displaystyle \frac {14} {20} $$
0%
$$\displaystyle \frac {20} {20} $$
0%
$$\displaystyle \frac {1} {20} $$
Explanation
The total marks are the denominator and the obtained marks are the numerator.
As he obtained $$14$$ marks out of $$20$$ the fraction form would be, $$\dfrac{14}{20}$$.
So option B is the correct answer.

Explanation
Let the left pizza$$=x$$
Asha ate $$\dfrac{1}{8}$$ of $$1$$ and Usha ate $$\dfrac{2}{8}$$ of $$1$$
The remaining pizza,$$x=1-\dfrac{1}{8}-\dfrac{2}{8}$$
$$=1-\dfrac{1+2}{8}$$
$$=1-\dfrac{3}{8}$$
$$=\dfrac{8-3}{8}$$
$$=\dfrac{5}{8}$$
The fractional part of the pizza left $$\displaystyle \frac {5}{8}$$
