22500 in words is "twenty-two thousand five hundred". Numbers are an integral part of our lives. They are used for counting everything around us. A number without any unit is just some number. But when we combine units and numbers together, we are able to count any physical quantity. So, number is the key to count things. To know how to write any digit in words we need to consider the place of each digit. Every number in the digit has it’s significance. A number in words tells us about the value of that the number holds.
To convert numbers to words, we need to be familiar with the decimal system of numbers. The decimal system of numbers is the number system that has a base of 10. It means all the digits are written using the power of 10. The decimal number system contains 10 numbers from 0-9. To write other numbers, we make use of power and the numbers 0-9. The value of the place in any number increases from left to right. The leftmost place has the lowest value, and the rightmost place has the highest value.
Step 1: Write all the places of the numbers
The place at the left end is considered the “unit place."
The place just before is “ten's place”
The place to the left of it is “hundreds place”.
Lakhs place | Ten thousands place | Thousands place | Hundreds Place | Tens place | Unit place |
{{10}^{5}} | {{10}^{4}} | {{10}^{3}} | {{10}^{2}} | {{10}^{1}} | {{10}^{0}} |
Step 2: multiply the number by it’s base to know the value of the digit.
For this case,
2 is in Ten thousands place
2 is in thousands place
5 is in hundreds
0 is in tens place and
0 is in unit place.
An even number is defined as any number that is completely divisible by 2. If a number, when divided by 2, leaves a remainder of 1, then the number is classified as an odd number.
22500 ÷ 2 = 11250
It gives zero remainder. Hence 22500 is an even number.
Prime numbers are the numbers that do not have factors. They cannot be written in form of multiplication of two ore more numbers except for 1 and the number itself.
22500 has factors. So, it is not a prime number.
A number that is used to count quantities is called as a cardinal number.
22500 can be used to count any physical quantities. Hence, it is a cardinal number.
Ordinal number is the number use to denote the place like 1st , 2nd, etc.
22500 can be used to denote 22500th place. Hence, it is an ordinal number.
If we take square root of 22500 we get 150 which is a whole number. So, it is a perfect square.
Every digit in a number has a value. If we interchange the digit, do we change the place of that digit, changing its value?
Any number having “0” in their unit place is divisible by 10.
The largest place in the given number is ten thousands place.
To find next even number we need to add 2. So, the next even number is 22502.
