Question

Which is the largest 3 digit number?

Answer 1

Hint: Take the largest digit, which is 9, place it in one place, tens place and hundreds place to get the largest three digit number.

Complete step-by-step answer:

We know that a single symbol used to make a number is known as a digit.
There are ten digits we use in our daily lives. They are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
We can take any combination of these ten digits to form a number. Like 345, 3556, 5350 and so on.
Here we have to find a three digit number. Three digits number means, in that number there will be three digits. Therefore, we can form so many three digit numbers by using these ten digits. But we have to find out the largest one.
We know that the largest digit is 9.
A three digit number is made of three places, which are the ones place, the tens place and the hundreds place. If we put the largest digit in all the three places we will get the largest three digit number.
Therefore, we have 9 ones, 9 tens and 9 hundreds.
9 ones = 9 times one = 9.
9 tens = 9 times ten = 90.
9 hundreds = 9 times hundred = 900.
Hence the number is:
900 + 90 + 9 = 999.
Therefore the largest three digit number is 999.

Note: If we need to find out the largest n digit number we have to put the largest digit, which is 9, in all the 9 places.
