In simple words: Look at each number and write down how you would say it out loud, using words. This helps you understand the value of each digit.

🎯 Exam Tip: Pay close attention to the place value of each digit (ones, tens, hundreds, thousands) when writing numbers in words. Remember to use hyphens for numbers between twenty-one and ninety-nine.

In simple words: For each word phrase, write the number using digits. Make sure to put a zero in any place value that is not mentioned, like in 'seventy-three' where there's no hundreds digit.

🎯 Exam Tip: When writing numerals from words, be careful about "and" (it usually signals tens and ones) and silent place values (like no hundreds means a zero). Practice reading numbers aloud to catch missing digits.

Question C. (i) Ramu went to a bank to deposit Rs. 7500. In the deposit form, he has to fill up the amount in words. Could you please help him?
Answer: The amount Ramu needs to fill in words is "Rupees seven thousand and five hundred only." This correctly states the full amount in both rupees and numerical words.
In simple words: Ramu needs to write "Rupees seven thousand and five hundred only" on the bank form.

🎯 Exam Tip: Always include the currency (like "Rupees") and the word "only" at the end when writing amounts in words for financial forms to prevent alteration.

Question C. (ii) Find the sum of the greatest two digit and the greatest three digit numbers. Write the number names of that sum.
Answer:
The greatest 2-digit number is 99.
The greatest 3-digit number is 999.
To find their sum, we add them together:
Sum = 99 + 999
Sum = 1098
The number name of the sum is "one thousand and ninety-eight." This combines the two numbers to show their total.
In simple words: The biggest 2-digit number is 99. The biggest 3-digit number is 999. Adding them gives 1098, which is "one thousand and ninety-eight."

🎯 Exam Tip: Remember that the "greatest" number for a certain number of digits is always made of all nines. Always double-check your addition before writing the number name.
