MULTIPLICATION OF FRACTIONAL NUMBER

__MULTIPLICATION OF FRACTIONAL NUMBER__

**1) Multiply 16 by 3/4**

**Step 1****.****
In the above problem/Multiplication, we can observe that in the first number there
is no ‘Denominator’, only ‘Numerator’ 16 is there. so, let us assume 1 is
‘Denominator’ of ‘Numerator’ 16, so the fraction is 16/1.**

**Step 2.**** Now, multiply all the ‘Numerator’ obtained from both fraction and like the same multiply all the ‘Denominator’ obtained from both fraction and you will
find a new fraction. 16 x 3 = 48 & 1 x 4 =
4 So, new fraction is 48/4.**

**Step.3**** Now simplify the new fraction 48/4 obtained from said the
multiplication via**** division method by the same prime number to ‘Numerator’ and
‘Denominator’ at a time again and again until it reaches to the prime number
itself (both Numerator & Denominator).**** **

**So, the desired answer is 12. (Ans.)**

**2) Multiply 4/5 by 5/16.**

**Step 1****.****
In the above problem/Multiplication, we can observe that, in first number 4 is
‘Numerator’ and 5 is ‘Denominator’. In second fractional number 5 is ‘Numerator’
and 16 is ‘Denominator’**

**Step 2.****
Now, multiply all the ‘Numerator’ obtained from both fraction and like
same multiply all the ‘Denominator’ obtained from both fraction And you
will find new fraction. 4 x 5 = 20 & 5 x 16 = 80. So, new
fraction is 20/80.**

**Step.3****
Now simplify the new fraction 20/80 obtained from said the
multiplication via division method by the same prime number to ‘Numerator’ and
‘Denominator’ at a time again and again until it reaches to the prime number
itself (both Numerator & Denominator).**

**So, the answer is 1/4 . (Ans.)**

**3) Multiply 7/9 by 4/11.**

**Step 1****.****
In the above problem/Multiplication, we can observe that, in first number 7 is
‘Numerator’ and 9 is ‘Denominator’. In the second fractional number 4 is
‘Numerator’ and 11 is ‘Denominator’.**

**Step 2.**** Now, multiply all the ‘Numerator’ obtained from both fraction and like the same multiply all the ‘Denominator’ obtained from both fraction and you
will find a new fraction. **

**7 x 4 = 28 & 9 x 11 =
99. **

**So, new fraction is 28/99.**

**Step.3**** Now simplify the new fraction 28/99 obtained from said the
multiplication via division method by the same prime number to ‘Numerator’ and
‘Denominator’ at a time again and again until it reaches to the prime number
itself (both Numerator & Denominator). But we can
observe that, no number can divide at a time both ‘Denominator’
& ‘Numerator’, so 28/99 is the simplest form and this is the
desired answer. (Ans.)**
