# Chapter 5 - Cumulative Review: 1

Answer: (a)- Natural numbers are => 11 and 112 (b)- Whole numbers are => 0 , 11 and 112 (c)- Integers are => -3 , -2 , 0 , 11 and 112 (d)- Rational numbers are=> $-3 ,-2 , 0 ,$ $\frac{1}{4}$ , $11$ and $112$ (e)- Irrational numbers => $\sqrt 2$ (f)- Real numbers => $-3 ,-2 , 0$ , $\frac{1}{4}$,$11$ and $112$ , $\sqrt 2$

#### Work Step by Step

a) Numbers greater than 0 are natural numbers. b) Numbers greater than or equal to 0 are whole numbers c) Numbers which either have a positive(+) sign or negative(-) before them are integers. d) All numbers that can be represented as a fraction (eg. $\frac{p}{q}$) are rational numbers. e) All numbers that cannot be denoted as a fraction, or whose decimal value is unending and non repeating are irrational numbers. f) All numbers lying on the number line are real numbers.
