## NCERT Solutions for Class 8 Maths Chapter 1 Exercise 1.2

In this page we have NCERT Solutions for rational Numbers Class 8 Maths Chapter 1 for Exercise 1.2 . Hope you like them and do not forget to like , social share and comment at the end of the page.
Question 1
Represent these numbers on the number line.
1. 7/4
2. -5/6 Question  2  Represent on the number line.  Question 3
Write five rational numbers which are smaller than 2.
2 can be written as $\frac {14}{7}$
So the five rational number smaller than
$\frac {8}{7}, \frac {9}{7},\frac {10}{7},\frac {11}{7},\frac {12}{7}$

Question 4
Find ten rational numbers between $-\frac {2}{5}$ and $\frac {1}{2}$
Creating same denominator of both the numbers
$-\frac {2}{5} = - \frac {8}{20}$
$\frac {1}{2}= \frac {10}{20}$
So ten rational numbers will be
$-\frac {7}{20},-\frac {6}{20},- \frac {5}{20} ,- \frac {4}{20} ,-\frac {3}{20},- \frac {2}{20},- \frac {1}{20}, 0 ,\frac {1}{20},\frac {2}{20}$
Question 5
Find five rational numbers between
(i) $\frac {2}{3}$ and $\frac {4}{5}$
(ii) $- \frac {3}{2}$ and $\frac {5}{3}$
(iii) $\frac {1}{4}$ and $\frac {1}{2}$
1. Creating same denominator $\frac {2}{3} = \frac {30}{45}$
$\frac {4}{5}= \frac {36}{45}$
So five rational number will be
$\frac {31}{45}, \frac {32}{45}, \frac {33}{46}, \frac {34}{45},\frac {35}{45}$
2. Creating same denominator $- \frac {3}{2}= - \frac {9}{6}$
$\frac {5}{3}= \frac {10}{6}$
So five rational number will be
$-\frac {8}{6},- \frac {7}{6},-1,- \frac {5}{6},- \frac {4}{6}$
3. Creating same denominator
$\frac {1}{4}= \frac {8}{32}$
$\frac {1}{2}= \frac {16}{32}$
So five rational number will be
$\frac {10}{32}, \frac {11}{32}, \frac {12}{32},\frac {13}{32}, \frac {14}{32}$
Question 6
Write five rational numbers greater than - 2.
-2 can be written as -14/7
So the five rational number smaller than
-8/7,-9/7,-10/7,-11/7,-12/7
Question 7
Find ten rational numbers between $\frac {3}{5}$ and $\frac {3}{4}$
$\frac {3}{5}= \frac {48}{80}$
$\frac {3}{4}=\frac {60}{80}$
So ten rational numbers are
49/80, 50/80, 51/80, 52/80, 53/80, 54/80, 55/80, 56/80, 57/80, 58/80
