NCERT Solutions for Class 6 Maths Chapter 7 Fractions Exercise 7.5

Question 1.
Write these fractions appropriately as additions or subtractions:

 (a) First fraction $$\frac{1}{5}$$ Second Fraction $$\frac{2}{5}$$ $$\frac{1}{5}+\frac{2}{5}=\frac{3}{5}$$ (Addition) Third Fraction $$\frac{3}{5}$$ (b) First fraction = $$\frac{5}{5}$$ Second fraction = $$\frac{3}{5}$$ Third fraction = $$\frac{2}{5}$$ $$1-\frac{3}{5}=\frac{2}{5}$$ (Subtraction) (c) First fraction = $$\frac{2}{6}$$ Second Fraction = $$\frac{3}{6}$$ Third Fraction $$\frac{5}{6}$$ $$\frac{2}{6}+\frac{3}{6}=\frac{5}{6}$$ (Addition)

Question 2.
Solve:
If the denominator is same, we can add and subtract the numerator

(g) Since 1 and $$\frac { 3 }{ 3 }$$ are equivalent fractions.
(h) $$\frac{1}{4}+\frac{0}{4}=\frac{1+0}{4}=\frac{1}{4}$$
∴ $$1-\frac{2}{3}=\frac{2}{3}-\frac{2}{3}=\frac{3-2}{3}=\frac{1}{3}$$

(i) Since 3 = $$\frac { 3 }{ 1 }$$, and equivalent fraction of $$\frac { 3 }{ 1 }$$ having denominator as 5 is given by

Question 3.
Shubham painted $$\frac { 2 }{ 3 }$$ of the wall space in his room. His sister Madhavi helped and painted $$\frac { 1 }{ 3 }$$ of the wall space. How much did they paint together?
Answre:
Space painted by them together = Space painted by Shubham + Space painted by Madhavi
= $$\frac{2}{3}+\frac{1}{3}=\frac{3}{3}=1$$
∴ Shubham and Madhavi together painted one complete wall in a room.

Question 4.
Fill in the missing fractions.
Javed was given $$\frac { 5 }{ 7 }$$ of a basket of oranges. What fraction of oranges was left in the basket?
Fraction of oranges given to Javed = $$\frac { 5 }{ 7 }$$
Fraction of oranges left in the basket = $$1-\frac{5}{7}=\frac{2}{7}$$
