## 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

ii. -11/6, -8/6,-7/6, -5/6,-2/6

Reference Books for class 8 Math

Given below are the links of some of the reference books for class 8 Math.

1. Mathematics Foundation Course for JEE/Olympiad : Class 8 This book can take students maths skills further. Only buy if child is interested in Olympiad/JEE foundation courses.
2. Mathematics for Class 8 by R S Aggarwal Detailed Mathematics book to clear basics and concepts. I would say it is a must have book for class 8 student.
3. Pearson Foundation Series (IIT -JEE / NEET) Physics, Chemistry, Maths & Biology for Class 8 (Main Books) | PCMB Combo : These set of books could help your child if he aims to get extra knowledge of science and maths. These would be helpful if child wants to prepare for competitive exams like JEE/NEET. Only buy if you can provide help to the child while studying.
4. Reasoning Olympiad Workbook - Class 8 :- Reasoning helps sharpen the mind of child. I would recommend students practicing reasoning even though they are not appearing for Olympiad.
