Mother baked a pan of pudding. She cut it into 10 equal parts.
What part of the whole is each of the equal parts?
You can write the name of each part as . You can also write it
in a
new way without changing its value. The fraction can also be
written as 0.1. This number is called decimal. It is a special kind
of fraction.
Two parts of the pudding can be written as 0.2; 3 parts is
written as
0.3; 4 parts is written as 0.4; and so on. Notice that you find
a dot at the left side of 1 (0.1), 2 (0.2), 3 (0.3), and 4 (0.4).
This dot is called decimal point. The decimal point tells that the
number is less than a whole or part of a whole.
The expression 0.2 is read as two-tenths .
The expression 0.3 is read as three-tenths The expression 0.4 is
read as four-tenths The digits 2, 3 and 4 are found or written one
place after the decimal
point. Therefore, the decimals 0.1, 0.2, 0.3 and 0.4 are called
one-place decimals.
0.5 is a one place decimal. You read it as five-tenths. How will
you read these one-place decimals? 0.6 0.8 0.9 0.7
