C. 20 (1/2)

Step-by-step explanation:

Let's find the value of the expression before looking for the nearest estimate

(19 4/5) (4/6) = 19 * (4/5) (4/6)

(19 4/5) (4/6) = 19 (16/30)

(19 4/5) (4/6) = 19 (8/15)

(19 4/5) (4/6) = (19*8) / 15

(19 4/5) (4/6) = 152/15

(19 4/5) (4/6) = 10 (2/15)

A. 16 (1/3) = 5.33

B. 19 (2/3) = 12.667

C. 20 (1/2) = 10

D. 20 (1) = 20

The nearest to the expression is C. 20 (1/2)
