Simplifying the fraction
To simplify the given expression first we have to convert the fractions into like fractions.
LCM of the denominators of the fractions is,
LCM (4,6,12)=2×2×3=12
Now, we will make the denominator of each fraction equal to LCM and simplify as follows:
14+56−112=1×34×3+5×26×2−112
=312+1012−112
=3+10−112
=1212=1
Therefore, the reduced form of the given expression is 1 .
