Multiply Fractions Calculator Multiply Fractions Calculator Let us first look at the fractions. Fractions are the numbers which can be expressed in the form of a / b, where a and b are the natural numbers and b <> 0. Here we say that a is the numerator and b is the denominator. Also we must remember that all the mathematical operations can be performed on the fraction numbers. These operations are addition, subtraction, multiplication and division. To work on Multiply Fractions Calculator, we mean that we need to learn about how to perform the multiplication operation on the fraction numbers. If we have two fraction numbers say a1/b1 and a2 / b2, then if the two fraction numbers are to be multiplied, then we say that the numerator is multiplied to the numerator and the denominator is multiplied to the denominator. Thus we say that here we write the product will be ( a1 * a2 ) / ( b1 * b2 ) So if the two fraction numbers are ( 4 /7) and ( 5 / 9) and we need to multiply them, then we say :

( 4 /7) * ( 5 / 9) =(4*5)/(7*9) = 20 / 63 The resultant fraction is the product of the two fractions. This fraction number can also be converted into its lowest form, which we say as the standard form of the fraction number. Now we will look at the properties of multiplication of the fraction numbers. 1. Multiplication of the fraction numbers satisfy the closure property of the fraction numbers. It means that if the two fraction numbers are multiplied, then the resultant fraction is also a fraction number. 2. Commutative property of multiplication also holds true for the two fraction numbers. It means that if the two fraction numbers are multiplied, then the product remains same, even if the order of their multiplication is changed. Thus we can write it mathematically as : ( a1/ b1 ) * ( a2 /b2 ) = ( a2 / b2 ) * ( a1 / b1). 3. Associative property of multiplication also holds true for the two fraction numbers. It means that if the three fraction numbers are multiplied, then the product remains same, even if the order of their multiplication is changed. Thus we can write it mathematically as : [ ( a1/ b1 ) * ( a2 /b2 ) ] * ( a3 / b3 ) = ( a1 / b1 ) * [ ( a2 / b2 ) * ( a3 / b3 ) ]

4. Multiplicative identity: A number 1 is the multiplicative identity for multiplication of any fraction number, which means that if any of the fraction number is multiplied with the number one, then we say that the result remains same. Thus if we have the fraction a/b, then a/b * 1 = a/b. 5. Power of zero: A number 0 is such a number, that if we multiply it by any of the fraction for multiplication of any fraction number, then we say that the result remains zero. Thus if we have the fraction a/b, then a/b * 0 = 0.
