Multiplying Mixed Numbers

In the previous session we discuss about Prime and Composite Numbers and now today we will discuss about Multiplying Mixed NumbersIn the mathematic a whole number is combined with a fraction is known as mixed number.
For example: 4 1 and 3 5
                        5          8
These are the examples of mixed fraction.
Now we will see process multiplying mixed numbers.
For multiplication of mixed fraction we have to follow some steps which are:
Step1: For the multiplication of mixed fraction firstly take a mixed number.
Step2: Then after change the mixed number into an improper fraction.
Step3: Then we write the number in multiplication order.
Step4: Then we will see the fraction values, if the values are divisible then we cancel the value otherwise we have to multiply numerator value of one fraction into another and multiply the denominator value to the other fraction.
Step5: At last again we get the result.
Suppose we have any mixed number 16 14/12 multiply to 10 8/14.
For the multiplication mixed numbers we have to follow all the above following steps:
Step1: firstly write the mixed number which is given:
   16 14/12 * 10 8/14;
Step2: Now we have to convert mixed number into improper fraction.
 = 206 148,
     12        14
Now multiply the numerator value of one fraction by another value and multiply denominator by other denominator value.
 = 206 * 148,
     12 * 14
On further solving we get:
⇒ 30488,
     168
Now divide the numerator value to the denominator value.
On dividing we get:
⇨ 181.47
On multiplication we get the 181.47.
Suppose we have any mixed number 8 7/10 multiply 4 8/9.
For multiplication of mixed numbers we have to follow all the above following steps:
Step1: firstly write the mixed number which is given:  
   8 7/10 * 4 8/9;
Step2: Now we have to convert mixed number into improper fraction.
 = 87 44,
    10     9
 = 87 * 44,
       90
Step4: Now multiply both the numerator and denominator values.
On multiplication we have:
⇒ 3696,
      90
On multiplication we get the 3696/90.
trigonometry calculator is a mathematical tool which makes the calculation so easy. For more detail see the Andhra Pradesh board of secondary education.
