Answer:
1 13/21
Step-by-step explanation:
It can work well to convert the numbers to improper fractions.
2 5/6 = (2·6 +5)/6 = 17/6
1 3/4 = (1·4 +3)/4 = 7/4
Division is the same as multiplication by the inverse:
(17/6) ÷ (7/4) = (17/6) × (4/7) = (17×4)/(6×7) = (17×2)/(3×7) = 34/21
34/21 = (21 +13)/21 = 1 13/21 . . . . convert back to mixed number

Additional comment
Note that a factor of 2 was removed from 4/6 to make it be 2/3. There are no other common factors in the products 17×4 and 6×7, so we know the result is in lowest terms.
