Ones, tens and hundreds are the places of digits in a number.

Identifying such Number

In any number, first number from right is called ones;

Second number from right is called tens;

And third digit from the right is called hundreds.

Identifying ones in a number.

In 35 first digit from right is 5. Thus the digit at one's place is 5. It is also said that 35 has 5 ones.

• Example:

18 has 8 ones because in 18, first digit from right is 8.

Identifying Tens in a Number

Here 21 is a number. In 21, 2 is at tens place. Second digit from right is the digit at tens place.

• Example:

In 43 the 2nd digit from right is 4 and hence, it is the digit at tens place. In this case it is also said 43 has 4 tens.

• Example:

In 34, the 2nd digit from right is 4 and hence it is at tens place.

Identifying Hundreds in a Number

In 120, the third digit from right is 'I'. Therefore, one is at hundreds place.
