## NCERT Solutions for Class 8 Maths Chapter 1 Rational Numbers Ex 1.2

**Ex 1.2 Class 8 Maths Question 1.**

Represent these numbers on the number line.

**(i)** \(\frac { 7 }{ 4 } \)

**(ii)** \(\frac { -5 }{ 6 } \)

**Solution:**

**(i)** For \(\frac { 7 }{ 4 } \), we make 7 markings of distance each on the right of zero and starting from 0. The seven marking is \(\frac { 7 }{ 4 } \).

The point P represents the rational number —.

**(ii)** For \(\frac { -5 }{ 6 } \), we make 5 markings of distance \(\frac { 1 }{ 6 } \) each on the left of zero and starting from 0. The fifth marking \(\frac { -5 }{ 6 } \) The point P represents the 6 rational number \(\frac { -5 }{ 6 } \).

**Ex 1.2 Class 8 Maths Question 2.**

Represent \(\frac { -2 }{ 11 } ,\frac { -5 }{ 11 } ,\frac { -9 }{ 11 } \) on the number line.

**Solution:**

To represent \(\frac { -2 }{ 11 } ,\frac { -5 }{ 11 } ,\frac { -9 }{ 11 } \) on a number line, draw a number line and mark a point O on it to represent zero. Now, mark a point P representing integers -1 on the left side of O on the number line.

Divide the segment OP into eleven equal parts. Let A, B, C, D, E, F, G, H, I, J be the points of division so that OA=AB =BC = … = JP. By construction, OB is two-eleventh of OP so B represents \(\frac { -2 }{ 11 } \) OE is five-eleventh of OP so E represents \(\frac { -5 }{ 11 } \) and OI is nine-eleventh of OP so I represents \(\frac { -9 }{ 11 } \).

**Ex 1.2 Class 8 Maths Question 3.**

Write five rational numbers, which are smaller than 2.

**Solution:**

Five rational numbers less than 2 may be taken

\(1,\frac { 1 }{ 2 } ,0,-1,\frac { -1 }{ 2 } \)

(There can be many more such rational numbers.)

**Ex 1.2 Class 8 Maths Question 4.**

Find ten rational numbers between \(\frac { -2 }{ 5 } \) and \(\frac { 1 }{ 2 } \).

**Solution:**

Converting the given rational numbers with the same denominators

**Ex 1.2 Class 8 Maths Question 5.**

Find five rational numbers between

**Solution:**

**(i)** Converting the given rational numbers with the same denominators

**(ii)** Converting the given rational numbers with the same denominators

**(iii)** Converting the given rational numbers with the same denominators

**Ex 1.2 Class 8 Maths Question 6.**

Write five rational numbers greater than – 2.

**Solution:**

Five rational numbers greater than -2 may be taken as

\(-\frac { 3 }{ 2 } ,-1,\frac { -1 }{ 2 } ,0,\frac { 1 }{ 2 } \)

There can be many more such rational numbers.

**Ex 1.2 Class 8 Maths Question 7.**

Find ten rational numbers between \(\frac { 3 }{ 5 } \) and \(\frac { 3 }{ 4 } \).

**Solution:**

Converting the given rational numbers with the same denominators
