1.3 Represent and order 9-digit numbers
The number symbol for two hundred and sixty-four million eight hundred 
and sixty-seven thousand five hundred and sixty-eight is 264 867 568.
It consists of three parts:           
                   264    867   568  
The first group of  
3 digits states the 
number of  
millions:  
264 millions.
The middle group of  
3 digits states 
the number of 
thousands:  
867 thousands.
The last group of  
3 digits states 
the number of 
hundreds, tens and 
units: 5 hundreds,  
6 tens and 8 units.
So, we can think of 264 867 568 as 264 million, 867 thousand and 568. 
The place value expansion (expanded notation) for 264 867 568 is
200 000 000 + 60 000 000 + 4 000 000 + 800 000 + 60 000 + 7 000 + 500 + 60 + 8.
1. How much is each of the following? Write the number symbols.
 (a) 217 458 379 - 458 000
 (b) 217 458 379 - 379
 (c) 217 458 379 - 217 million
 (d) 217 458 379 - fifty thousand
 (e) 217 458 379 - three hundred
 (f) 300 million + 30 million + 30 thousand
 (g) 300 million + 3 million + 3 thousand
 (h) 300 million + 30 million + 3 thousand
 (i) 300 million + 30 thousand + 3 hundred
 (j) 30 million + 30 thousand + 3 hundred
 (k) 3 million + 30 thousand + 3 hundred

FAQs on Textbook: Whole Numbers (Term 2) - Mathematics for Grade 6

1. What are whole numbers, and how do they differ from integers?
Ans. Whole numbers are a set of numbers that include all the natural numbers (0, 1, 2, 3,...) along with zero. They do not include any negative numbers or fractions. Integers, on the other hand, include all whole numbers as well as their negative counterparts. So, integers consist of positive whole numbers, negative whole numbers, and zero.
2. How do you add and subtract whole numbers?
Ans. To add whole numbers, you simply combine the values together. For example, 3 + 5 = 8. To subtract whole numbers, you take one number away from another. For instance, 8 - 5 = 3. Make sure to line up the numbers correctly if dealing with larger values to avoid mistakes.
3. What are the properties of whole numbers?
Ans. The properties of whole numbers include: 1. Closure Property: The sum or product of any two whole numbers is always a whole number. 2. Commutative Property: The order in which you add or multiply whole numbers does not change the result (e.g., a + b = b + a). 3. Associative Property: The way in which you group the numbers when adding or multiplying does not affect the result (e.g., (a + b) + c = a + (b + c)). 4. Identity Property: The sum of a whole number and zero is the whole number itself, and the product of a whole number and one is the whole number itself.
4. How can I represent whole numbers on a number line?
Ans. To represent whole numbers on a number line, start by drawing a horizontal line. Mark evenly spaced points along the line, starting from zero and then continuing with whole numbers (1, 2, 3, etc.) to the right. To the left of zero, you will not have any whole numbers since they are non-negative. Each point represents a whole number, and you can use the number line to visualize addition and subtraction.
5. Why are whole numbers important in everyday life?
Ans. Whole numbers are important in everyday life because they are used in various practical situations, such as counting objects, measuring quantities, and tracking time. Whether you are shopping, cooking, or managing finances, whole numbers help in making calculations, budgeting, and organizing information without the need for fractions or decimals.
