Answer:
2/-3 ÷ 2 3/4
Convert the mixed fraction to an improper fraction
2/-3 ÷ 11/4
Change the division sign to multiplication sign ( × ) and reverse the second fraction
That's
2/-3 × 4/11
= -8/33

Answer: 12 hours
Step-by-step explanation:
s = the time of the smaller plow.
In one hour, the larger can do 1/4 of a lot, right? Then, the smaller plow can do 1/s of a lot.
Working together to do 1 lot, we multiply their rates by the time.
1/4(3) + 1/s(3) = 1
3/4 + 3/s = 1
The common denominator is 4s, so...
3s/4s + 12/4s = 1
With a common denominator, we can now combine the numerators...
(3s+12)/4s = 1
We multiply both sides by 4s...
3s + 12 = 4s
12 = s
So, it would take the smaller plow 12 hours to clear the lot by itself.
