Important Questions on 9th Maths Chapter 1
Is zero a rational number? Can you write it in the form p/q, where p and q are integers and q≠0?
Yes, zero is a rational number. It can be written in the form of p/q. For example: 0/1, 0/2, 0/5 are rational numbers, where p and q are integers and q≠0.
Simplify each of the following expression: (3 + √3)(2 + √2)
(3 + √3)(2 + √2)
= 6 + 3√2 + 2√3 + √6
Find six rational numbers between 3 and 4.
Six rational numbers between 3 and 4 are 3.1, 3.2, 3.3, 3.4, 3.5 and 3.6.
Express 0.99999… in the form of p/q . Are you surprised by your answer?
0.99999… Let x = 0.99999… … (i) Multiplying equation (i) by 10 both sides 10x = 9.99999… ⇒ 10x = 9 + 0.99999…… ⇒ 10x = 9 + x [From equation (i)] ⇒ 10x – x = 9 ⇒ 9x = 9 ⇒ x = 9/9 = 1 The answer makes sense as 0.99999… is very close to 1, that is why we can say that 0.99999=1.
Write three numbers whose decimal expansions are non-terminating non-recurring.
Three non-terminating non-recurring decimals: 0.414114111411114… 2.01001000100001… π=3.1416…
