Reading and Writing Large Numbers

In reading and writing large numbers we group place values into periods ‘ones or unit’, ‘tens’, ‘hundred’, ‘thousand’, ‘10 thousand’, ‘100 thousand’, ‘million’, ’10 million’, ‘100 million’, ‘billion’, ’10 billion’, ‘100 billion’, ‘trillion’ are periods.

For example:

Ones/Unit = 1

Tens = 10

Hundred = 100

Thousand = 1,000

10 Thousand = 10,000

100 Thousand = 100,000

Million = 1,000,000

10 Million = 10,000,000

100 Million = 100,000,000

Billion = 1,000,000,000

10 Billion = 10,000,000,000

100 Billion = 100,000,000,000

The below diagram will help us to get the better concept on facts about reading and writing large numbers.

So, while reading or writing a large number we need to start from the left side with the largest group and move to the right side.

Large Numbers

We have studied the following pattern regarding the smaller numbers:

Let us extend the same pattern to get the larger numbers:

We observe that the value of each place increases 10 times as we move one place from right to left, i.e., ones to tens, tens to hundreds, hundreds to thousands, etc.

However, to read numerals of larger numbers without difficulty, we group the places into periods in the place value chart.

These periods are usually separated by commas (,).

Frequently asked questions on Reading and Writing Large Numbers:

1. The total number of 6-digit number is

(a) 9,000

(b) 90,000

(c) 9,00,000

(d) 900

Solution:

Greatest six-digit number = 9,99,999

Greatest five-digit number = 99,999

Total number of six-digit numbers 9,99,999 - 99,999 = 9,00,000

So, the option (c) is correct, which is the required answer, i.e., answer (c).

2. How many 5-digit numbers are there in all?

Solution:

Greatest five-digit number = 99,999

Greatest four-digit number = 9,999

Total number of five-digit numbers 99,999 - 9,999

                                               = 90,000

3. The total no. of 8-digit numbers is

(i) 9999999

(ii) 90000000

(iii) 10000000

(iv) 99999999

Solution:

Greatest eight-digit number = 9,99,99,999

Greatest seven-digit number = 99,99,999

Total number of five-digit numbers 9,99,99,999 - 99,99,999

                                               = 9,00,00,000
