Answer 2

To subtract the given mixed numbers, we need to find a common denominator for each subtraction operation. Let's perform the calculations step by step:

First, we'll subtract the whole numbers: 8 - 3 = 5

Next, let's subtract the fractions. To find a common denominator for 7/15 and 2/524, we can multiply the denominators together: 15 * 524 = 7860

Converting 7/15 and 2/524 to have a common denominator of 7860: (7/15) * (524/524) = 3668/7860 (2/524) * (15/15) = 30/7860

Now, we can subtract the fractions: 3668/7860 - 30/7860 = (3668 - 30)/7860 = 3638/7860

Finally, let's subtract the whole numbers again: 5 - 19 = -14

Now, we'll combine the result from the whole numbers with the fraction: -14 + 3638/7860

To simplify this mixed number, we can reduce the fraction by finding the greatest common divisor (GCD) of the numerator and denominator: GCD(3638, 7860) = 2

Dividing both the numerator and denominator by 2: 3638/2 = 1819 7860/2 = 3930

The simplified mixed number is -14 1819/3930.
