NCERT Solutions for Class 6 Maths Chapter 7 Fractions Exercise 7.5
Question 1.
Write these fractions appropriately as additions or subtractions:
Answer:
| (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:
Answer:
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.
Answer:
Question 5.
Javed was given \(\frac { 5 }{ 7 }\) of a basket of oranges. What fraction of oranges was left in the basket?
Answer:
Fraction of oranges given to Javed = \(\frac { 5 }{ 7 }\)
Fraction of oranges left in the basket = \(1-\frac{5}{7}=\frac{2}{7}\)
