Answer:
When you are adding or subtracting a negative fraction, you usually want to consider the numerator as negative. The method is just the same, except now you may need to add negative or positive numerators.
Example 1:
Find the sum.
95+(−43)
The LCM of 5 and 3 is 15 .
To add the fractions with unlike denominators, rename the fractions with a common denominator.
95=9 × 35 × 3=2715−43=−4 × 53 × 5=−2015
So,
95+(−43)=2715+(−2015)
Since the denominators are the same, add the numerators.
=27+(−20)15=715
