Rational and Irrational Numbers Introduction
Introduction - The sets of numbers which every student must remember are: The set of natural numbers N = {1, 2, 3, 4, 5, } The set of whole numbers W = {0, 1, 2, 3, 4, 5,} The set of integers Z = I = {, -3, -2, -1, 0, 1, 2, 3,} T..

To mark , an irrational number, on the number line. Let OA = AB = 1 unit and Then in rt. = 1 + 1 Cut off OP = OB = on the number l..1st method:
9x - 4x = 13y + 11y 5x = 24 y Squaring both sides, (Componendo and Dividendo) Again ..
9x - 4x = 13y + 11y 5x = 24 y Squaring both sides, (Componendo and Dividendo) Again ..Decimals
Every fraction with denominator 10 can be written in decimal notation. 1/10 can be written as 0.1 in decimal notation.The dot represents the decimal point and it come between the units place and the tenths place. One will read this as zero point one..
Approximation
Approximation - We know that the digits of a number, one by one in order from left to right decrease in value rapidly. Let us illustrate it by examples. Mass of a gold ornament is 23.473 g. Round off to (i) two decimal places, (ii) one decimal place. 23.473 g..

Ratio is the numerical relation of one quantity to another of the same kind. To find the ratio of 2 m 25 cm to 75 cm, we first change 2 m 25 cm into cm, which equals 225 cm. Now, we have to find 225 cm to 75 cm ratio is = 3 : 1 We can write the above ratio as (i) 3 : 1..
