Ones Tenths Hundredths

Introduction to Ones Tenth Hundredths:

These ones, tenths and hundredths are representing the place value of the number. The number which has place value of ones is the number less than ten. That is the number in place value of ones  starts from 0 to 9. The number which has the place value of tenths is that number multiplied by `(1)/(10)` . The number which has the place value of hundredths is that number multiplied by `(1)/(100)` .

Ones Tenths Hundredths:

The standard form of place value exists in decimal number and fraction form. Generally in decimal number, digit place before the decimal point is called as ones and digit after the decimal point is called as tenths and digit after the tenths place is called as hundredths.

Example: x.yz, here

x is the digit placed before the decimal point – Ones.

y is the digit placed after the decimal point – Tenths = x *`(1)/(10)`

z is the digit placed after the tenths place – Hundredths = y * `(1)/(100)`

Example Problem – Ones Tenth Hundred:

Example 1:

Write the place value of ones in following numbers.

a)      2.9

b)      1123

c)      0.01

Solution:

a) 2.9

Given the number is the decimal number, and the digit before the decimal point is 2.

2 is the number having ones Place.

Answer: 2

b) 1123

Here the given number is not the decimal number, it is the whole number.

Step 1: Make the whole number as decimal number without changing the value as 1123.0

Now the ones place of the number 1123 is 3

Answer: 3

c) 0.01

Given the number is the decimal number, and the digit before the decimal point is 0.

0 is the number having ones Place.

Answer: 0

Example 2:

Say the ones tenth and hundredths of the following numbers.

a)      2.34

b)      17.456

Solution:

a) 2.34

The digit before the decimal point = 2 = Ones

The digit after the decimal point = 3 = tenths

The digit after the tenths place = 4 = hundredths.

b) 17.456

The digit before the decimal point = 7 = Ones

The digit after the decimal point = 4 = tenths

The digit after the tenths place = 5 = hundredths.
