Answer:

first, find the LCM between the two fractions, and multiply each fraction by the appropriate factor so that the denominator becomes LCM for both fractions

then, since they have different signs, add the negative numerator to the positive numerator, and their sum would be the final numerator. if the magnitude of the positive number is bigger than the negative number, the final fraction will be positive, otherwise it will be negative

Step-by-step explanation:

  1. You must find the LOWEST Common Multiple [LCM] between the two denominators.
  2. After finding the Lowest Common Multiple, whichever fraction is the greatest, you take the sign of that fraction, then simplify [if necessary].
