Whole Numbers and Place Value in Grade V

Hello friends,Previously we have discussed about probability worksheets and  today we are going to discuss one of the important topics of math grade V of cbse syllabus which is whole numbers and place value. Whole numbers are the set of familiar numbers (0, 1, 2, 3, 4, and so on). When they are called counting numbers, zero is not included. The whole numbers are also called the positive integers (or the nonnegative integers, if zero is included) and they plays an important role to solve math problems.
The numbers 0, 1, 2, 3, ... etc.

There is no or decimal part and no negatives. We will begin our review of place values with a look at whole numbers. When writing large numbers it is a common practice to separate them into groups of three using commas as the separator. When separating into groups of three, start from the right and count toward the left.
Example: 3, 79 and 980 are all whole numbers.
Place value is the value of a digit as determined by its position in a number. The name of the place or location of a digit in a number. The ability to understand place values is an important mathematics skill measured in the Early Childhood Longitudinal Study. More specifically, students should be able to identify place values in integers to the hundreds place to achieve this skill. Simply the Place Value is the position of a digit in a number written in standard form determines the actual value the digit represents.This table shows the place value for various position (want to Learn more about Whole Numbers ,click here),
Place (underlined) Name of Position
1 000 Ones (units) position
1 000 Tens
000 Hundreds
1 000 Thousands
1 000 000 Ten thousands
000 000 Hundred Thousands
1 000 000 Millions
1 000 000 000 Ten Millions
000 000 000 Hundred millions
1 000 000 000 Billions
We will take some examples for explanation.
Example:
The number 521092 has a 5 in the hundred thousands place, a 2 in the ten thousands place, 1 in the thousands place, 0 in the hundredths place, 9 in the tens place, and a 2 in ones place.
Example:
Four billion, sixty million, six hundred twenty thousand
4,060,620,000
And another example
9,568,125
Numbers, such as 9,568,125 have seven digits.  Each digit has a different place value.
The first digit is called the millions' place value. There are nine millions in the number 9,568,125
The second digit tells you how many sets of one hundred thousand are in the number.  The number 9,568,125 has five hundred thousand.
The third digit is the ten thousands' place. There are six ten thousands in addition to the nine millions and five hundred thousand.
The fourth digit is the one thousands' place which is eight in this example.
The fifth digit is the hundreds' place which is one in the number 9,568,125.
The next digit two is the tens' place.
The last or right digit is the ones' place which is five in this example.
Therefore, there are nine sets of 1,000,000, five sets of 100,000, six sets of 10,000, eight sets of 1000, one sets of 100, two sets of 10, and 5 ones in the number 9,568,125.

Example :In the numeral 7,015,384, what digit is in the...
  Ques                                                           Answer
a) Ones place ?                                                   4
b) ten thousands place ?                                     1
c) tens place ?                                                     8
d) millions place ?                                               7
e) hundreds place ?                                            3
f) hundred thousands place ?                             0
g) thousands place ?                                           5
So here we end with whole numbers and place value. I hope that this article will help you in solving problems related to whole numbers and place value and if anyone wants to know about Number systems in Grade V and Percentages in Grade VI then they can refer Internet.
