Step 3: Convert both fractions to have the common denominator of 510. (82/15) * (34/34) = 2788/510 (144/34) * (15/15) = 4320/510

Step 4: Subtract the fractions with the same denominator. 2788/510 - 4320/510 = -1532/510

Step 5: Simplify the fraction (if possible). The fraction -1532/510 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 34. (-1532/34) / (510/34) = -46/15
