Answer 3

To subtract the two mixed numbers, we need to find a common denominator for the fractions. The common denominator is the least common multiple (LCM) of the denominators. In this case, the denominators are 27 and 81.

To find the LCM of 27 and 81, we can simplify the numbers first:

27 = 3^3 81 = 3^4

The highest power of 3 between the two numbers is 3^4, so the LCM of 27 and 81 is 3^4 = 81.

Now, let's convert the mixed numbers to improper fractions:

6 5/27 = (6 * 27 + 5) / 27 = 162/27 3 20/81 = (3 * 81 + 20) / 81 = 263/81

Now, we can subtract the fractions:

162/27 - 263/81

To subtract fractions, we need a common denominator. Since the denominators are already the same, we can subtract the numerators directly:

(162 - 263) / 81 = -101/81

Therefore, the result of the subtraction 6 5/27 - 3 20/81 is -101/81.
