## 2. Place value of a decimal number:

Decimal numbers are fractions or mixed numbers with denominators of powers of ten.

In a decimal number, the digits to the left of the decimal point represent a whole number. The digits to the right of the decimal represent the parts. The place value of the digits becomes 10 times smaller.

The first digit on the right of the decimal point means tenths i.e. 1/10ths.

In 27.356,
27 is the whole number part,
2 is in ten's place and its place value is 20,
7 is in one's place, and its place value is 7.

There are three digits to the right of the decimal point,
3 is in the tenth's place, and its place value is 0.3 or 3/10
5 is in the hundredth's place, and its place value is 0.05 or 5/100
6 is in the thousandth's place, and its place value is 0.006 or 6/1000.

= 25.7

#### Example

Given the place value table, write the number in decimal form.

 Thousands Hundreds Tens Ones Tenths Hundredths Thousandths 0 1 9 7 6 8 0

1 × 100 + 9 × 10 + 7 × 1 + 6/10 + 8/100

⇒ 100 + 90 + 7 + 6/10 + 8/100

⇒ 197 + (60 + 8)/100

⇒ 197 + 68/100

⇒ 197 68/100

⇒ 197.68

#### Example

Given the place value table, write the number in decimal form.

 Thousands Hundreds Tens Ones Tenths Hundredths Thousandths 7 3 2 1 0 8 9

7 × 1000 + 3 × 100 + 2 × 10 + 1 × 0 + 8/100 + 1/1000.

= 7000 + 300 + 20 + 1 + 0 + 8/100 + 1/1000.

= 7321 + (80 + 9)/1000

= 7321 + 89/1000

= 7321 89/1000
