Arnav’s father is filling petrol in his motorcycle at a nearby petrol pump.

These are decimal numbers.
The dot in a decimal number
is called a decimal point.

What types of numbers are
shown on the machine? Why
is there a dot? I am unable
to read the numbers. Here, `435.24 can be read
as rupees ‘four hundred
thirty-five point two four’
and 4.5 L as ‘four point
five’ litres.
