Explanation:

Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,


(x)/(y) * (a)/(b )= (x*a)/(y*b)

Addition and subtraction requires that we find a common demoninator.

For example,


(6)/(4) + (4)/(3)

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.


(6)/(4)*(3)/(3) + (4)/(3) (4)/(4) = (18)/(12)+(16)/(12)

Then we add the numerators


(18+16)/(12) = (32)/(12)

Then we should reduce.


(16)/(6) = (8)/(3)

Division is a little trickier because we have to flip-flop the second term and then multiply. For example:
(1)/(10) / (5)/(6) \rightarrow (1)/(10) * (6)/(5) = (6)/(50)
