As is evident from the example the process of division is not complete and the process
continues indefinitely. Hence such decimals are termed as infinite or recurring decimals.
The idea may be explained to the child through Braille text material.
- Like decimals
Numbers which have same number of decimal places are called like decimals.
Eg. : 7.8 and 4.5
1.234, 3490.567 and 198765.543 etc.,.
The idea may be explained through practice using the columns of the abacus.
- Unlike decimals
Numbers which do not have same number of decimal places are called unlike decimals.
Eg. : 3.98, 2.5 and 45.098765 etc.,
The idea may be explained through practice using relevant text material in Braille.
- Conversion to like decimals
A given set of decimals can be converted to like decimals by attaching sufficient
number of zeros to the right of it.
Eg. : Convert the following into like decimals: 1.008, 9.7, 11.7654, 0.123456
Here the maximum decimal place is 6, that is in 0.123456
Therefore, 1.008 = 1.008000
9.7 = 9.700000
11.7654 = 11. 765400
The idea may be explained orally assisted by relevant text material in Braille. The
abacus is useful to explain this concept as the decimal point placement starts from
the dots on the separation bar and the digits are placed on the right side of the dots.
