To subtract the fractions 2 5/7 and 2/3, we need to convert the mixed number to an improper fraction.
2 5/7 = (2 * 7 + 5) / 7 = 19/7
Now, let's find a common denominator between 7 and 3, which is 21.
Therefore, (19/7) - (2/3) = (19/7) * (3/3) - (2/3) * (7/7)
= (57/21) - (14/21)
= (57 - 14) / 21
= 43/21
The result is 43/21.
