800
There are 52 weeks in the year, so since 2 weeks are taken off, they only work 50 weekends a year, which is a total of 100 days. 100 days x 8 hours is 800 hours total
The easiest way to compare fraction is to make them all have the same denominator and then you can just compare the numerators...
-1/6, (5/3)(2/2), -5/6
-1/6, 10/6, -5/6 so from least to greatest
-5/6, -1/6, 10/6
-5/6, -1/6, 5/3
I hope this helps you, I just took this quiz so it is correct.
The ratio of interest can be found for collinear points by considering only one of the coordinates. Let's look at the x-coordinates.
(Tx -Mx)/(Dx -Mx) = (1-(-3))/(9-(-3)) = 4/12 = 1/3
Then the ratio of interest is MT:MD = 1:3.
