6-digit numbers are natural numbers in which the first digit should be 1 or greater than 1 and the rest of the digits can be any number between 0 and 9. 6 digit numbers are mostly used to express larger quantities like the population of a state, or the price of cars. In this lesson, we will explore the world of numbers up to 6 digits. We will walk through the Indian and International numbering systems for the numbers up to 6-digits, see how to decompose them, clear misconceptions, and discover an interesting 6-digit number. Show
What are 6 Digit Numbers?In 6-digit numbers, the highest place value has a unique name in the Indian numeral system - a lakh. A lakh (1,00,000) is 1 followed by 5 zeros and it is the smallest possible 6-digit number. It is essential to understand the Indian numbering system at this stage because from the next higher place value (or the next higher power of ten), the International numbering system would also be used, so the difference must be made clear. There are three special numbers in the Indian numbering system - Lakh, Crore, and Arab.
Observe the Indian Place Value Chart given below which shows the place value up to ten arab.  There is no particular name for a lakh in the International system, and it is simply referred to as a hundred thousand. Let us have a look at the International Place Value Chart given below which shows the place values up to hundred million. Commas in 6-Digit NumbersAs per the Indian numbering system, there would be two commas used in any six-digit number. The first would demarcate the first three digits (from right) to show how many thousands there are, and the next would come after the first 5 digits from the right to show how many lakhs are there in the number. For example, you would write 372672 as 3,72,672 to mean that the number has 3 lakhs, 72 thousand, 6 hundred, 7 tens, and 2 ones. How to Decompose 6 Digit Numbers?Decomposition of a 6-digit number means to write that number with the help of its place value and face value. Like we said at the start, a 6-digit number has place values up to a lakh. Given below are the names of the place values (starting from the right) in a 6-digit number:
So let us take a random 6-digit number like 2,31,273 (Indian System) and 231,273 (International System) and see how it gets decomposed.
Now, observe the decomposition of the same number as per the International Place Value Chart. The Expanded form is useful to split and present the higher digit number in its units, tens, hundreds, thousands form. Decomposition of numbers leads to writing or reading of numbers in an expanded form which further helps to better understand and rightly read the higher digit numbers. The number 2,31,273 can be written in expanded form as 2,00,000 + 30,000 + 1,000 + 200 + 70 + 3. The Significance of Zero in 6 Digit NumbersAny zero which does not have any non-zero number to its left does not count in the digits of the 6-digit number. Take, for example, two 6-digit numbers 023843 and 002305. In both these numbers, the 6th number on the extreme left does not have any further non-zero number to its left. Additionally, in 002305, the 5th number from the right also does not have any further non-zero number to its left. So for 002305, the two numbers on the left extreme are without any value. So the two numbers can actually be written as 23843 (which makes it a 5-digit number) and 2305 (which makes it a 4-digit number). On the other hand, with the addition of each zero to the right of any digit in the number, increase the value of that number, such as 238430 (which is a 6-digit number) becomes 2384300, which is a 7-digit number. An Interesting 6-digit numberAs you continue to explore your way around the exciting world of numbers, you will come across a number that usually is written using 6 digits (although shorter versions are also used). This number is called'Pi' (pronounced as Pie) and is represented as 3.14159 and the Greek letter π. It is defined as the ratio between a circle’s circumference and its diameter. So, if the diameter is D, and circumference is C, then C = πD. In more simple terms, it is the ratio of the number 22 and the number 7. Although it is usually represented by six digits (and sometimes even smaller versions like 3.14 or 3.142), it is theoretically possible to have infinite digits in this number. Now we come to the interesting part. Instead of 22/7, let us consider 1/7. This number 1/7 is another cyclic number (it has infinite numbers after the decimal point), but we usually write it as 0.142857. Here are some amazing facts about 0.142857
Common Mistakes or MisconceptionsRight from early grades, children face difficulties regarding the place value of digits in the given numbers and then they come across learning of the number system and conversions from one number system to another. Here children should build comfort writing the same number in both systems. Targeted practice helps. Given below are common mistakes and misconceptions.
Let us now understand how to write a 6-digit number in the Indian as well as the International System. Place Value of 6 Digit NumbersThe best way to learn to write 6-digit numbers is to create a chart with all the place names listed. You must have observed that till ten thousand the naming convention is the same. But for 6 digits or higher the same number has two names. The choice of names does not change the value of the number. “One lakh” and “one hundred thousand” are equal (have the same value). Also, the given numbers can be represented in the standard form, words, or in the expanded form. Tips and Tricks on 6 Digit Numbers
"one crore" is 1 followed by 7 zeros.
