The horizontal distance between E and F is:
dx = 11 - 4 = 7
The vertical distance between E and F is:
dy = abs (4 - 8) = 4
Since the ratio is 1:5, that means there are 6 equal parts of line EF. Dividing the distances by 6,
dx/6 = 1.1667
dy/6 = 0.6667
Since point R is located below and to the right of point E, we add dx/6 to the x coordinate and subtract dy/6 from the y coordinate of E:
R(4+1.1667, 8-0.6667) = R (5.17, 7.33)
The answer is the 3rd option.
total, t = 15/16
red beans, r = 3/16
pinto beans, p = 5/16
black beans, b = t -(p+r) = 7/16
I calculated and got 314.16
