concerned the place value of the digits starting from the left is one-tenth, one-
hundredth, one-thousandth and so on.
To enable the child to understand the concept, provide the child with an abacus and
the purpose of the dots in the abacus could be explained emphasizing their significance
in the abacus.
- Decimal part
In a decimal number the digits which appear after the decimal point collectively
constitute the decimal part. The idea may be explained orally supported by relevant
text material in Braille.
- Finite (terminating) decimal
In the expression of a rational number if the process of division is complete, that is
upon dividing and if the remainder is zero then the decimal so formed is a finite
decimal.
The idea can be explained to the child through demonstration.
Eg : 85 = 0. 625
Here the process of division is complete after a certain stage and hence the decimal
formed is finite or terminating decimal.
- Infinite (recurring) decimal ( Periodic decimal)
In expressing a rational number if the process of division is incomplete, that is upon
dividing if the remainder is not equal to zero then the decimal so formed is said to be
an infinite or recurring decimal.
Eg. : 31 = 0. 3333333 .......
71 =^ 0.142857^ 142857...
