Large Number

Here we will discuss how to read and write large numbers.

Reading a large number:

In order of reading a large number, of a five digit number, we must separate the digits according to the period. 

(i) 72418

Starting from the right, separate the ONES period by marking a comma after three places as the ONES period has three places. 

The numbers formed by the digits in one period are read together, along with the name of the period. 

Seventy two thousand four hundred eighteen

(ii) 36432

Thirty six thousand, four hundred thirty two

(iii) 40219

Forty thousand, two hundred nineteen

(iv) 51708

Fifty one thousand, seven hundred eight

(v) 29161

Twenty nine thousand, one hundred sixty one

Ones, tens, hundreds which belong to the ONES period.

Thousand, ten thousand which belong to the THOUSANDS period.

The number represented in the first example is 12452 and read as:

Twelve thousand, four hundred fifty two

The number represented in the second example is 20275 and read as:

Twenty thousand, two hundred seventy five

Note: ‘And’ is not used in a number line.

Writing large numbers:

1. To write the numerals for; eighty nine thousand seven hundred four, we write the digits in a place value chart.

Then we write the numeral, using a comma to separate the ONES from the THOUSANDS 89,704. 

To read and write a large number like 6 digit, 7 digit numerals.

In the place value chart, the sixth place is that of hundred thousands and the seventh place is of millions.

To read and write six or seven digit numerals we will need to use commas in two places.

One comma to separate the ONES and THOUSANDS period and one comma to separate the THOUSANDS and MILLIONS period.

Writing Large Numbers in Figures

2. Write the number-five lakh, five thousand, six hundred twenty-nine in figures.

We proceed as follows:

Step I: Make three periods as shown below.

The first period from the right will have three parts, the second will have parts and the third will have only one part.

Step II: Write all the lakhs in the first period from the left.

Step III: Write all the thousands in the second period from the left. We fill all the parts. For example, if it is 5 thousand, we write 05.

Step IV: Write the hundreds, tens and ones in the third period from the left.

Thus, five lakh, five thousand six hundred twenty-nine in figures is 5,05,629.

Place Value: 

A numeral gets its value according to the place it is located in. Each digit has a face place and a place value. The face value is the digit itself. The face value multiplied by the value of the location gives the place value.

The face value of 5 is 5. The place value is 5 tens or 50

The place value of

8 = 8 × 1 = 8 Ones = 8

4 = 4 × 10 = 4 Tens = 40

9 = 9 × 100 = 9 Hundreds = 900

4 = 4 × 1000 = 4 Thousands = 4000

2 = 2 × 10000 = 2 Ten Thousands = 20000
