Number Names Rules 1 to 50
[Click Here for Sample Questions]
RULE 1: Understanding the position of the digit. The positional value of the digit will tell you how the digit should be spelt. Positions of the digits can be as follows:
- 1 – Ones
- 10 – Tens
- 100 – Hundreds
- 1000 – Thousands
RULE 2: Number names from 1-20 follow a different pattern. Numbers after 20 follow a repeated pattern. For example: - 9 = Nine; 12 = Twelve and on the other hand 21 = Twenty-One; 37 = Thirty-Seven.
RULE 3: In order to easily understand the writing of the number names, expanding the numbers or breaking the numbers can be done. For example: if you have to express 23 in words then you can also write it as 20 + 3 = Twenty + Three. But this is the case only with numbers after 20 to 99.

Forming Numbers
In forming numbers from given digits, the conditions under which the numbers are to be formed are satisfied. Thus, to form the greatest four-digit number from 7, 8, 3, and 5 without repeating a single digit, we need to use all four digits, the greatest number can have only 8 as the leftmost digit.
The smallest four-digit number is 1000 (one thousand). It follows the largest three-digit number 999. Similarly, the smallest five-digit number is 10,000. It is ten thousand and follows the largest four-digit number 9999. Further, the smallest six-digit number is 100,000. It is one lakh and follows the largest five-digit number 99,999. This carries on for higher digit numbers in a similar manner.
Remember kilo shows 1000 times larger, Centi shows 100 times smaller and the milli shows 1000 times smaller, thus, 1 kilometer = 1000 meters, 1 meter = 100 centimeters or 1000 millimeters, etc.

Ques. In one state, the number of bicycles sold in the year 2002-2003 was 7,43,000. In the year 2003-2004, the number of bicycles sold was 8,00,100. In which year were more bicycles sold? And how many more? (3 marks)
Ans. Clearly, 8,00,100 is more than 7,43,000.
So, in that state, more bicycles were sold in the year 2003-2004 than in 2002-2003.
Now, 800,100 – 743,000 = 57,100
Around 57,100 bicycles were sold.

Ques. The number of sheets of paper available for making notebooks is 75,000. Each sheet makes 8 pages of a notebook. Each notebook contains 200 pages. How many notebooks can be made from the paper available? (3 marks)
Ans. Each sheet makes 8 pages.
Hence, 75,000 sheets make 8 × 75,000 pages,
Now, 75000 × 8 = 600000
Thus, 6,00,000 pages are available for making notebooks.
Now, 200 pages make 1 notebook.
Hence, 6,00,000 pages make 6,00,000 ÷ 200 notebooks
The answer is 3,000 notebooks.
