- Reducing a fraction to its lowest terms
To reduce a fraction to its lowest form, both the numerator and denominator should
be either divided by all their factors in succession or divided by their G.C.D. once.
The process of reducing a fraction to its lowest terms is to be explained to the child
clearly supported by necessary text material in Braille. To master the idea, the child
needs to be given adequate practice in reducing a fraction to its lowest terms on his/
her own.
- Addition, Subtraction, Multiplication and Division of Fractions
For addition, subtraction, multiplication and division of fractions, follow the procedures
described in abacus calculations (Modules 6 to 13).
- Multiplicative inverse
If the product of two fractions is equal to 1, then each of the fractions is said to be
the multiplicative inverse of the other.
Eg. : Consider the fraction 75
Note that 75 ×^75 =^1
Therefore, the multiplicative inverse of 75 is 57 and the multiplicative inverse of 57
is 75.
