Question 1
1 / -0

This is a whole cake

A
$$\displaystyle \frac {2}{4}$$

B
$$\displaystyle \frac {2}{6}$$

C
$$\displaystyle \frac {2}{7}$$

D
$$\displaystyle \frac {2}{8}$$

Solution

Guru left two parts.
Total parts = 8
$$\therefore$$ Required fraction = $$\displaystyle \frac {2}{8}$$
Question 2
1 / -0

This is a whole.

A
$$\displaystyle \frac {1}{3}$$

B
$$\displaystyle \frac {3}{8}$$

C
$$\displaystyle \frac {2}{3}$$

D
$$\displaystyle \frac {5}{8}$$

Solution

$$\displaystyle \frac {3}{8}\, +\, \displaystyle \frac {2}{8}\, =\, \displaystyle \frac {3+2}{8}\, =\, \displaystyle \frac {5}{8}$$
Question 3
1 / -0

Pankaj scored 14 marks out of 20. Its fractional form is -

A
$$\displaystyle \frac {8} {20} $$

B
$$\displaystyle \frac {14} {20} $$

C
$$\displaystyle \frac {20} {20} $$

D
$$\displaystyle \frac {1} {20} $$

Solution

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.
Question 4
1 / -0

A fraction with a numerator less than the denominator is called a proper fraction.
Which of the following is shaded to represent a fraction with a value EQUAL TO the one above?

A

B

C

D

Solution

The given figure represents three equal parts shaded out of $$6$$ parts and the same thing is represented in option $$B$$ only difference is that in the given figure blocks are shaded alternatively but in option $$B$$ they are shaded continuously which is not a matter of concern as of now. Hence, option $$B$$ is correct.
Question 5
1 / -0

How many of the star in the group below must be shaded to represent a fraction with the same value.
The picture below is shaded to represent a fractional number.

A
$$5$$

B
$$6$$

C
$$8$$

D
$$10$$
Question 6
1 / -0

In the word GOPAL, what fraction of alphabets are made of three lines?

A
$$\displaystyle \frac {2}{5}$$

B
$$\displaystyle \frac {1}{5}$$

C
$$\displaystyle \frac {3}{5}$$

D
$$\displaystyle \frac {4}{5}$$

Solution

only "A" is made of three lines.
So, required fraction = $$\displaystyle \frac {1}{5}$$
Question 7
1 / -0

Asha and Usha shared a pizza. Asha ate $$\displaystyle \frac {1}{8}$$ of the pizza and Usha ate $$\dfrac28$$ of the pizza. Which picture shows how much pizza was left?

A

B

C

D

Solution

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 $$\displaystyle \frac {5}{8}$$
Question 8
1 / -0

Which of the following figure is divided into four equal parts?

A

B

C

D

Solution

Ans-option D
Circle is divided in to four equal parts.
Question 9
1 / -0

Madhavi made the following design using squares.
What fractional part of the design is shaded?

A
$$\displaystyle \frac {5}{12}$$

B
$$\displaystyle \frac {7}{12}$$

C
$$\displaystyle \frac {5}{6}$$

D
$$\displaystyle \frac {12}{5}$$

Solution

Number of shaded parts = 5
Total parts = 12
So, the fraction is $$\displaystyle \frac {5}{12}$$
