Maharashtra Board Solutions Class 8-Maths (Practice Set 1.1): Chapter 1- Rational and Irrational Numbers

Maharashtra Board 8th Maths Chapter 1, Class 8 Maths Chapter 1 solutions

Question 1.
Show the following numbers on a number line. Draw a separate number line for each example.
i. 32,52,−32
ii. 75,−25,−45
iii. −58,118
iv. 1310,−1710
Solution:
i. 32,52,−32

Here, the denominator of each fraction is 2.
∴ Each unit will be divided into 2 equal parts.

ii. 75,−25,−45

Here, the denominator of each fraction is 5.
∴ Each unit will be divided into 5 equal parts.

iii. −58,118

Here, the denominator of each fraction is 8.
∴ Each unit will be divided into 8 equal parts.

iv. 1310,−1710

Here, the denominator of each fraction is 10.
∴ Each unit will be divided into 10 equal parts.

Question 2.
Observe the number line and answer the questions.

i. Which number is indicated by point B?
ii. Which point indicates the number 134 ?
iii. State whether the statement, ‘the point D denotes the number 52 is true or false.
Solution:
Here, each emit is divided into 4 equal parts.
i. Point B is marked on the 10th equal part on the left side of O.
∴ The number indicated by point B is −104.

ii.

Point C is marked on the 7th equal part on the right side of O.
∴ The number 134 is indicated by point C.

iii. True
Point D is marked on the 10th equal part on the right side of O.
∴ D denotes the number 104=5×22×2=52
