## Rajasthan Board RBSE Class 8 Maths Chapter 1 Rational Numbers Ex 1.1

Question 1.

Add the following rational numbers. (Solve any two on number line)

Solution:

Distance between two consecutive numbers on number line is

So,addition of with means, addition of with

We have to move three gaps from in left side (being negative(RBSESolutions.com) sign of )

So, we reach finally at

Distance gap between two(RBSESolutions.com)consecutive points on number line is . Therefore, addition of with 0 means, we have to move 2 gaps in left side from zero, so we reach finally at

Hence, 0 + =

Question 2.

Find the value (Solve any two on number line)-

Solution:

Distance between two points (gaps) on number line is

So, addition of and means we have to move 15 gaps in right side (being positive sign of So, we reach at finally.

Solution on number line-

Distance(RBSESolutions.com)between two points (gaps) on

Number line is

S0, addition of and means we have to move 15 gaps in left side negative sign of So, we reach at finally.

Hence

(ix) When rational number is added with its additive inverse then result is always ___(zero/same)

(x) When rational number is divided by same rational number then result is always ____(zero/one)

Solution:

(i) Rational

(ii) positive

(iii) undefined

(iv) zero

(v) one

(vi) reciprocal

(vii) left

(viii) right

(ix) zero

(x) one.
