How to Divide Mixed Numbers

In the previous session we discuss about Multiplying Mixed Numbers and now today we will discuss about How to Divide Mixed Numbers. We know that the mixed fractions are the numbers which are formed by the combination of whole number and the proper fraction. Now we will learn about how to divide mixed numbers.  Let us first take a mixed number divided by the whole number. In this situation, we will first convert the mixed fraction to improper fraction. Now to divide the improper fraction by the whole number, we will first convert the whole number to its reciprocal and then multiply the reciprocal to the improper fraction and get the quotient. Let us take the example as follows:  2 ¼ divided by 3
On converting 2 ¼ into mixed fraction, we get 9 / 4 and the reciprocal of 3 is 1/ 3.
 Now we proceed  by multiplying  9/4 by 1/3 , we get :  ( 9/ 4 ) * ( 1/3 )  = 9 / 12  = 3 / 4
 So we say that when 2 ¼ is divided by 3, we get  3 /4 Ans.
If we have a mixed fraction divided by a mixed fraction, we will convert both the mixed fractions   to improper fractions and then we write it in the form of:
 Dividend   divided by divisor = quotient
So we will convert the above expression by changing the divisor as its reciprocal and changing the  sign of division to multiplication. So it can be expressed as:
  Dividend *  ( reverse of divisor ) = quotient
 Once if the quotient is calculated, we check that if the is improper fraction, then we will express in the form of a mixed fraction, which will be the result of division.
We will learn about how to solve the Absolute Value Equations by visiting online math tutor. We can know about CBSE syllabus by visiting the site of CBSE and collecting the details.
