CBSE Important Questions Class 6 Maths Chapter 7 – Fractions

Q1. A rope is 100 m long. If 1/5 of the rope is cut off, what is the length of the remaining rope? Explain your steps.

Answer: Total length of the rope = 100 m
Length of the rope cut = 1/5 of 100 m = (1/5) × 100 m = 20 m
Length of the remaining rope = Total length − Length cut
= 100 m − 20 m = 80 m
Therefore, the length of the rope left is 80 m.

A 100 m rope in five equal parts of 20 m with one part cut off

Q2. A tank is 3/4 full and holds 200 L when full. How much water is in it now?
(a) 100 L
(b) 150 L
(c) 175 L
(d) 200 L

Answer: (b) 150 L
Capacity of the tank when full = 200 L
Water in the tank now = 3/4 of 200 L = (3/4) × 200 = 150 L

Q3. 1/5 of a 100 m rope is cut. How much is left?
(a) 20 m
(b) 40 m
(c) 50 m
(d) 80 m

Answer: (d) 80 m
Length of the rope = 100 m
Length cut = (1/5) × 100 = 20 m
Rope left = 100 − 20 = 80 m

Q4. If 1/3 of 45 students are absent, how many are present?
(a) 30
(b) 25
(c) 15
(d) 35

Answer: (a) 30
Total students = 45
Students absent = (1/3) × 45 = 15
Students present = 45 − 15 = 30

Q5. How many more 1/5's need to be added to 1/5 + 1/5 + 1/5 + 1/5 + 1/5 + 1/5 to convert this into an exact (whole) number?
(a) 1
(b) 2
(c) 3
(d) 4

Answer: (d) 4
1/5 added six times gives 6/5, which is 1 and 1/5. It is not a whole number.
The next whole number is 2, which is 10/5.
10/5 − 6/5 = 4/5, so 4 more fifths are needed.

Q6. Anu, Bina and Chitra share a chocolate bar. Anu gets 1/3 of it and Bina gets 2/5 of it. What fraction does Chitra get?

Answer: Chitra's share = 1 − 1/3 − 2/5
First make the denominators the same. The LCM of 3 and 5 is 15.
1/3 = 5/15 and 2/5 = 6/15
Anu and Bina together get 5/15 + 6/15 = 11/15
Chitra's share = 15/15 − 11/15 = 4/15
So, Chitra gets 4/15 of the chocolate bar.

Chocolate bar of 15 equal parts shared between Anu, Bina and Chitra

Q7. Rahul claims that 19/5 is greater than 19/4 as the denominator of the first one is greater than the second. Is Rahul correct?

Answer: No, Rahul is not correct.
When the numerator is the same, a bigger denominator means the whole is cut into more pieces, so each piece is smaller. In other words, 1/5 is smaller than 1/4.
It is like sharing the same thing among 5 people instead of 4 people — the more people there are, the less each one gets.
So, 19/5 is less than 19/4, that is, 19/5 < 19/4.

Q8. If you fold a square paper into 4 equal parts and then fold each part into 3 equal parts, what fraction of the original square is each small part?

Answer: After the first fold, each part is 1/4 of the square.
Each of these parts is then folded into 3 equal parts, so each small part = (1/4) × (1/3) = 1/12.
We can also count directly: 4 × 3 = 12 equal parts in all.
So, each small part is 1/12 of the original square.

Square divided into 12 equal parts, one part shaded as 1/12

Q9. A water tank is 2/3 full. If 1/4 of the water is used, what fraction of the tank remains filled?

Answer: Water used = (1/4) of (2/3) = (1/4) × (2/3) = 2/12 = 1/6 of the whole tank.
Fraction of the tank that remains filled = 2/3 − 1/6
The LCM of 3 and 6 is 6, so 2/3 = 4/6.
= 4/6 − 1/6 = 3/6 = 1/2
So, 1/2 of the tank remains filled.

Tank two-thirds full before and half full after one-fourth of the water is used

Q10. Rohan spent 2/5 of his money on books and 1/4 of his money on stationery. What fraction of his money is left? Is it more or less than half?

Answer: Total money spent = 2/5 + 1/4
The LCM of 5 and 4 is 20, so 2/5 = 8/20 and 1/4 = 5/20.
Total spent = 8/20 + 5/20 = 13/20
Money left = 1 − 13/20 = 20/20 − 13/20 = 7/20
Now compare with half: 1/2 = 10/20. Since 7/20 < 10/20, the money left is less than half.
So, 7/20 of his money is left, and it is less than half.

Q11. A rectangular sheet is divided into equal parts. If 3/8 of the sheet is coloured red and 2/5 of the sheet is coloured blue, what fraction of the original sheet is neither red nor blue?
(a) 40/31
(b) 31/40
(c) 9/40
(d) 40/9

Answer: (c) 9/40
Red + blue = 3/8 + 2/5
The LCM of 8 and 5 is 40, so 3/8 = 15/40 and 2/5 = 16/40.
Red + blue = 15/40 + 16/40 = 31/40
Part that is neither red nor blue = 1 − 31/40 = 40/40 − 31/40 = 9/40

Q12. If 3/5 of a number is 27, then 2/3 of the same number is
(a) 10
(b) 20
(c) 30
(d) 40

Answer: (c) 30
First find the number. If 3/5 of the number is 27, then the number = 27 ÷ (3/5) = 27 × (5/3) = 45.
Now, 2/3 of 45 = (2/3) × 45 = 30

FAQs (Frequently Asked Questions)

CBSE Important Questions Class 6 Maths Chapter 7 focus on fractions. The chapter explains equal shares, fractional units, mixed fractions, equivalent fractions, and operations.

Fractional units are single equal parts of a whole. Examples include 1/2, 1/3, 1/4, and 1/10.

A fraction can be less than, equal to, or greater than 1. A mixed fraction has a whole part and a fractional part, such as 2 1/3.

Equivalent fractions help compare, add, and subtract fractions. For example, 1/2 = 2/4 = 3/6.

Brahmagupta’s method uses common denominators for fraction addition and subtraction. Example: 1/4 + 1/3 = 3/12 + 4/12 = 7/12.
