Chapter 6: Fractions – Exercise 6.8 Question: 1 Write these fractions appropriately as additions or subtraction: Solution: Question: 2 Solve: Solution: i) The given fractions are: Hence the answer is 3/5 ii) The given fractions are: Hence the answer is 4/3 iii) the given fractions are: Hence the answer is 5/11 iv) the given fractions are: Hence the answer is 1/4 v) The given fractions are: Hence the answer is 7/13 vi) the given fractions are: Hence the answer is 1/5 vii) the given fractions are: Hence the answer is 12/31 viii) the given fractions are: Hence the answer is 1/1 = 1 ix) the given fractions are: Hence the answer is 5/1 = 5 x) the given fractions are: Hence the answer is 8/3 xi) the given fractions are: Hence the answer is 20/7 Question: 3 Shikha painted 1/5 of the wall space in her room. Her brother ravish helped and painted 3/5 of the wall space. How much did they paint together? How much the room is left unpainted? Solution: Shikha painted 1/5 of the wall space in her room Ravish painted 3/5 of the wall space Wall space painted by both of them together Unpainted part of the room Question: 4 Ramesh bought sugar whereas rohit boughtof sugar. Find the total amount of sugar bought by both of them. Solution: Quantity of sugar bought by ramesh = Quantity of sugar bought by rohit = Total amount of sugar bought by them: Quantity of sugar bought by rohit + Quantity of sugar bought by ramesh = 6 kg (Dividing numerator and denominator by their HCF (6)) Question: 5 The teacher taught 3/5 of the book, Vivek revised 1/5 more on his own. How much does he still have to revise? Solution: Fraction of the book taught by the teacher = 3/5 Fraction of the book revised by vivek = 1/5 Fraction of the book still left for revision by vivek: Therefore, Fraction of the book still left for revision by vivek is 2/5 Question: 6 Amit was given 5/7 of a bucket of oranges. What fraction of oranges was left in the basket? Solution: Fraction of oranges given to amit = 5/7 Fraction of oranges left in the basket: Therefore, Fraction of oranges left in the basket is 2/7 Question: 7 Solution: i) Given: Therefore, ii) Given: Therefore, iii) Given: Therefore, iv) Given: Therefore,
Write these fractions appropriately as additions or subtraction:
Solve:
i) The given fractions are:
Hence the answer is 3/5
ii) The given fractions are:
Hence the answer is 4/3
iii) the given fractions are:
Hence the answer is 5/11
iv) the given fractions are:
Hence the answer is 1/4
v) The given fractions are:
Hence the answer is 7/13
vi) the given fractions are:
Hence the answer is 1/5
vii) the given fractions are:
Hence the answer is 12/31
viii) the given fractions are:
Hence the answer is 1/1 = 1
ix) the given fractions are:
Hence the answer is 5/1 = 5
x) the given fractions are:
Hence the answer is 8/3
xi) the given fractions are:
Hence the answer is 20/7
Shikha painted 1/5 of the wall space in her room. Her brother ravish helped and painted 3/5 of the wall space. How much did they paint together? How much the room is left unpainted?
Shikha painted 1/5 of the wall space in her room
Ravish painted 3/5 of the wall space
Wall space painted by both of them together
Unpainted part of the room
Ramesh bought sugar whereas rohit boughtof sugar. Find the total amount of sugar bought by both of them.
Quantity of sugar bought by ramesh =
Quantity of sugar bought by rohit =
Total amount of sugar bought by them:
Quantity of sugar bought by rohit + Quantity of sugar bought by ramesh
= 6 kg (Dividing numerator and denominator by their HCF (6))
The teacher taught 3/5 of the book, Vivek revised 1/5 more on his own. How much does he still have to revise?
Fraction of the book taught by the teacher = 3/5
Fraction of the book revised by vivek = 1/5
Fraction of the book still left for revision by vivek:
Therefore, Fraction of the book still left for revision by vivek is 2/5
Amit was given 5/7 of a bucket of oranges. What fraction of oranges was left in the basket?
Fraction of oranges given to amit = 5/7
Fraction of oranges left in the basket:
Therefore, Fraction of oranges left in the basket is 2/7
i) Given:
Therefore,
ii) Given:
iii) Given:
iv) Given:
