1 5/6 × 2= 2.66 or 2 2/3.
HOPE THIS HELPS!!!!
You would get 9e+46 so not a real answer, just an estimate of what the answer is.
Consider inequality
This inequality is equivalent to inequality 
This means that 
The greatest integer number n, such that
when dividing by 7 gives the remainder 4 is 39. Then subtract 7, you get 32, then 25 and so on.
When n=-39, -32, -25, -18, -11, -4, 4, 11, 18, 25, 32, 39 then dividing by 7 the remainder is 4.
Answer: 12 integers.
I think the answer is A but I could be wrong
