rePresentation of decimal nUmbers on a Place valUe chart

We know that when we move from right to left in the place value chart, the value of the
respective place increases 10 times.

Also, we can say that when we move from left to right in the place value chart, the value
of the respective place decreases 10 times.
Now, if we extend the place value chart to the right of the ones place, the place value at
the places to the right of the ones place will be fractional. The place value of the immediate

right place after the ones place is tenths 1 and to the right of the tenths place, the
10
place value is hundredths 1 and so on.

place digit using a dot (.) or decimal point. Each

place to the right of the decimal point is called a decimal place.
For example:

Tens Ones Tenths Hundredths
(10) (1) • 1 1
10 100

(a) 4 • 1 2

(b) 1 0 • 0 7
(c) 4 8 • 8 1

(d) 9 9 • 9 9
We write and read these decimal numbers as follows:

( a) 4.12: Four point one two (b) 10.07: Ten point zero seven
( c) 48.81: Forty-eight point eight one (d) 99.99: Ninety-nine point nine nine

Example 1: Write the following decimal numbers in the numeral form.
( a) Two point zero nine

( b) Three point seven two Math Insight
( c) Fifty point one nine We do not read the digits
to the right of the decimal
( d) Seventy-three point zero three point together.
( e) Eighty-four point six

Teacher’s Explain to the students the difference between “tens and tenths”, “hundreds and hundredths”, etc.
