NCERT Solutions for Class 6 Maths Ganita Prakash Chapter 7 – Fractions

NCERT Solutions for Class 6 Maths Chapter 7 – Fractions explain the "Fractions" chapter of the Ganita Prakash book in plain, simple language. A fraction is what we use when one whole thing is shared into equal parts. This chapter starts with simple sharing — three guavas weighing 1 kg together, or three rotis shared among four children — and builds from there.

Students learn to write fractions from pictures, mark them on a number line, find how many whole units are in an improper fraction, change mixed numbers into fractions, and use a fraction wall to spot equivalent fractions. The chapter also connects fractions to division, addition and multiplication facts. These solutions are useful for students starting the chapter, for parents helping at home, and for teachers preparing class work. A free printable PDF of these solutions is also available for download.

[Image: Q7_question_pictograph.png]

Answer:

(a)

Fractional Units

1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 6 times half
1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 7 times half

  • 1/8 → the circle divided into 8 equal parts, with 1 part shaded

Q11. What is the length of the blue line and black line shown below? The distance between 0 and 1 is 1 unit long, and it is divided into two equal parts. The length of each part is 1/2. So, the blue line is 1/2 units long. Write the fraction that gives the length of the black line in the box.

Answer:
Length of blue line is 1/2.
Length of black line is 1/2 + 1/2 + 1/2
Fraction that gives length of black line = 3/2

Q12. Here, the fractional unit is dividing a length of 1 unit into three equal parts. Write the fraction that gives the length of the blue line in the box or in your notebook.

Answer:
Here number line OR is divided into three equal parts OP, PQ and QR.
Hence length of blue line = OP + PQ = 1/3 + 1/3 = 2/3

Q13. Here, a unit is divided into 5 equal parts. Write the fraction that gives the length of the blue lines in the respective boxes or in your notebook.

Answer:
Here number line from 0 to 1 unit is divided into five equal parts.
Hence length of the first blue line from bottom = 1/5 + 1/5 = 2/5
Now, length of the second blue line from bottom = 1/5 + 1/5 + 1/5 + 1/5 = 4/5

Q14. Now, a unit is divided into 8 equal parts. Write the appropriate fractions in your notebook.

Answer:
Here number line OH is divided into 8 equal parts OA, AB, BC, CD, DE, EF, FG and GH.

Hence, OA = 1/8, OB = 2/8, OC = 3/8, OH = 8/8 = 1

Q15. On a number line, draw lines of length 1/10, 3/10 and 4/5.

Answer:

Q18. Write the fraction that gives the lengths of the black lines in the respective boxes.

Answer:

The fractions are 6/5, 7/5, 8/5, 9/5 and 2 (or 10/5). Note that 1 can also be written as 5/5.

Q19. How many whole units are there in 7/2?

Answer:
7/2 = 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 3 + 1/2
So, there are 3 whole units in 7/2.

Q20. How many whole units are there in 4/3 and in 7/3?

Answer:
4/3 = 1/3 + 1/3 + 1/3 + 1/3 = 1 + 1/3
So, there is 1 whole unit in 4/3.

7/3 = 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 2 + 1/3
So, there are 2 whole units in 7/3.

Q21. Figure out the number of whole units in each of the following fractions:
(a) 8/3 (b) 11/5 (c) 9/4

Answer:
(a) 2
(b) 2
(c) 2

Q22. Can all fractions greater than 1 be written as such mixed numbers?

Answer:
Yes.

Q23. Write the following mixed numbers as fractions:
(a) 3¼ (b) 7⅔ (c) 9 4/9 (d) 3⅙ (e) 2 3/11 (f) 3 9/10

Answer:
(a) 3¼ = (3 × 4 + 1)/4 = 13/4
(b) 7⅔ = (7 × 3 + 2)/3 = 23/3
(c) 9 4/9 = (9 × 9 + 4)/9 = 85/9
(d) 3⅙ = (3 × 6 + 1)/6 = 19/6
(e) 2 3/11 = (2 × 11 + 3)/11 = 25/11
(f) 3 9/10 = (3 × 10 + 9)/10 = 39/10

Q24. Answer the following question after looking at the fraction wall: Are the lengths 1/2 and 3/6 equal?

Answer:
Yes, here lengths 1/2 and 3/6 = 1/2.
Lengths are equal.

Q25. Answer the following question after looking at the fraction wall: Are 2/3 and 4/6 equivalent fractions? Why?

Answer:
Yes, lengths 2/3 and 4/6 = 1/3 are equivalent fractions, as they have the same length.

Q26. Answer the following question after looking at the fraction wall: How many pieces of length 1/6 will make a length of 1/2?

Answer:
Total no. of pieces = (1/2) ÷ (1/6) = (1/2) × (6/1) = 6/2 = 3
Hence three pieces of length 1/6 will make a length of 1/2.

Q27. Answer the following question after looking at the fraction wall: How many pieces of length 1/6 will make a length of 1/3?

Answer:
Total no. of pieces = (1/3) ÷ (1/6) = (1/3) × (6/1) = 6/3 = 2
Hence two pieces of length 1/6 will make a length of 1/3.

Q28. Are 3/6, 4/8 and 5/10 equivalent fractions? Why?

Answer:
Here, simplest form of 3/6 = (3 ÷ 3)/(6 ÷ 3) = 1/2 [HCF of 3 and 6 is 3]
and simplest form of 4/8 is (4 ÷ 4)/(8 ÷ 4) = 1/2 [HCF of 4 and 8 is 4]
and simplest form of 5/10 is (5 ÷ 5)/(10 ÷ 5) = 1/2 [HCF of 5 and 10 is 5]
Hence, 3/6, 4/8 and 5/10 are equivalent fractions.

Q29. Write two equivalent fractions for 2/6.

Answer:
From the fraction wall we can choose any two fractions that denote the same length as 2/6:
2/6 = 1/3 = 3/9

Q30. Three rotis are shared equally by four children. Show the division in the picture and write a fraction of how much each child gets. Also, write the corresponding division facts, addition facts, and multiplication facts.

Answer:
One roti is shared as shown in the figure below:

The four shares must be equal to each other!
Similar distribution will be done for the second and third roti also.
So, each child will get 3/4 a piece of roti.
The division fact is 3 ÷ 4 = 3/4
The addition fact is 3 = 3/4 + 3/4 + 3/4 + 3/4
The multiplication fact is 3 = 4 × 3/4

Q31. Draw a picture to show how much each child gets when 2 rotis are shared equally by 4 children. Also, write the corresponding division facts, addition facts, and multiplication facts.

Answer:
One roti is shared as shown in the figure below:

The four shares must be equal to each other!
A similar distribution will be done for the second roti also.
So, each child will get 1/4 part from a roti.
So, the total fraction of roti received by each child from 2 rotis = 2/4 = 1/2
The division fact is 2 ÷ 4 = 2/4
The addition fact is 2 = 2/4 + 2/4 + 2/4 + 2/4
The multiplication fact is 2 = 4 × 2/4

Q32. Anil was in a group where 2 cakes were divided equally among 5 children. How much cake would Anil get?
