-2 divided by 2 5/6<br> (make a fraction and simplify)
seropon [69]

Answer:

−12/17

Step-by-step explanation:

This is the answer because:

1) First, convert 2 5/6 to an improper fraction

2 5/6 = 17/6

2) Next divide -2/1 and 17/6

3) The reciprocal of 17/6 is 6/17

4) -2/1 ÷6/17 is -12/17

Hope this helps!
