Class 8 Math Chapter 1 Rational Number Ex 1.2-NCERT

Ex 1.2 Class 8 Maths Question 1.
Represent these numbers on the number line
1) 7/4

2) -5/6$$

Solution:
(i) 

Here, point A represents [Math Processing Error] on the number line.
(ii) 

Here, point B represents [Math Processing Error] on the number line.

Ex 1.2 Class 8 Maths Question 2.
Represent -10/11, 5/11, -2/11 on a number line.

Solution:

Ex 1.2 Class 8 Maths Question 3.
Write five rational numbers which are smaller than 2.

Solution:
Write 2 with same denominator:

Example:$$2 = \frac{10}{5}$$

Now take fractions less than 10/5​:$$\frac{9}{5},\; \frac{8}{5},\; \frac{7}{5},\; \frac{6}{5},\; \frac{5}{5}$$

Ex 1.2 Class 8 Maths Question 4.
Find ten rational numbers between -2/5 and 1/2

Solution:

Ex 1.2 Class 8 Maths Question 5.
Find five rational numbers between
(i) 2/3 and 4/5
(ii) -3/2 and 5/3
(iii) -9/6 and 10/6

Solution:

Ex 1.2 Class 8 Maths Question 6.
Write five rational numbers greater than -2.

Solution:
Write $-2$−in fraction form:$$-2 = \frac{-2}{1}$$

Now, any rational number to the right of -2 on the number line (i.e., bigger than -2) will be correct.

$$-1,\; -\frac{3}{2},\; -\frac{4}{3},\; -\frac{5}{4},\; -\frac{7}{6}$$

Ex 1.2 Class 8 Maths Question 7.
Find ten rational numbers between 3/5 and 3/4.

Solution:
Given rational numbers are [Math Processing Error] and [Math Processing Error].
