The fraction 4/6 could represent the green
If you just want to solve for h, as it appears, isolate h by dividing both sides of the equation by 6.25.
That leaves h = 16. (16 hours, presumptively).
1/3=2/6
-1/6= -1/6
then I guessing you add them?
2/6+-1/6=1/6
3/4
2/4=1/2= 2x2=4 1x2=3
1/4 stays the same
2/4+1/4=3/4
prices?
This will help a lot if you know how to do proportions... hope I helped
