SUBTRACTION OF FRACTIONAL NUMBER

__SUBTRACTION OF FRACTIONAL NUMBER__

**Step.1**** - first find LCM of ‘Denominators’ 12 & 24. **

**LCM = 2 x 3 x 3 x (2
x 3) = 108**

**So, LCM of 36 &
54 = 108, put 108 as ‘Denominator’ at next step.**

**Step.2****
– Divide by denominator of 1 ^{st} fraction to LCM, after
getting the quotient from this divide, multiply it’s ‘Numerator’ with the obtained
quotient. 108 ÷ 54 = 2 ; 5 X 2 = 10. So, 10 the new ‘Numerator’ of 1^{st} fraction.**

**Step.3****
– Divide by denominator of 2 ^{nd} fraction to LCM, after
getting the quotient from this divide, multiply it’s ‘Numerator’ with the obtained
quotient. 108 ÷ 36 = 3 ; 4 X 3 = 12. So, 12 is the new ‘Numerator’
of 2^{nd} fraction.**

**Step.4****
– Now subtract between two new ‘Numerator’ obtained from
two Separate fraction. 12 – 10 = 2 . so, 2 is the new
‘Numerator’ So, the answer is 2/108.**
