Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)
The answer is .85
$17/$20
=.85
You have to do 2h up, halph an hour parallel
, and then a line more vertical than the 2h, then parallel the time he is on the top, and then a line down that stops parallel for some time in the middle and then a line down to the bottom.
There you are almost but you have to do it with better measures.
