Hey There!
Here is your answer:
First write the equation down:
-3 4/5 ÷ -3 1/6
Then put the mixed fractions into whole numbers:
-3 4/5= 5×-3=-15+4=-11= -11/5
&
-3 1/6= 6×-3=-18+1=-17= -17/6
Now right the new problem:
-11/5×6/-17
Now multiply:
-11×6=-66
5×-17=-85
Which means -66/-85 is your answer!
Hope this helps!

X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.
So, now that you have y, you can plug it into the first equation to find x:
So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
