how to multiply fractions

In the previous section we have discussed about how to add fractions and In today's session we are going to discuss about how to multiply fractions, All mathematical operators can be performed on the fraction numbers. We will learn about how to multiply fractions. For multiplying the fraction numbers, we say that in order to multiply the fraction numbers, we say that a fraction number is expressed in the form of a / b, then we say that the if we have two fraction numbers, say a1/b1 and a2/b2, then we say that the product of two fraction numbers can be calculated in the form, such that the numerators of both the fraction numbers are multiplied and the denominators of both the fractions are subtracted. So we get the fraction such that the result appears as follows:
    ( a1 * a2 ) / ( b1 * b2 )
 Now let us look at the following example: If we have two fractions such that a1/b1 = 2/5 and a2 / b2 = 10/15. Then we say that the product of the two numbers is ( a1/b1 ) * ( a2/b2 ) and its result will be :
( a1/b1 ) * ( a2/b2 ) = ( 2/5 ) * ( 10 / 15 )
 = ( 2 * 10 ) / ( 5 * 15 )
= 20 / 75
 Now we will divide both the numerators and the denominators by 5 and we get :
= ( 20 ÷ 5 ) / ( 75 ÷ 5 )
= 4 / 15
 So we observe that the product of the two numbers  2/5 and 10 /15  is  4 / 15.
  The product of the fractions is converted into their lowest form to get the result of multiplication in the standard form.
