Simple calculation:

= (12/9) - (9/12)

= (4/3) - (3/4)

= (16-9)/12

= 7/12

What is $$\frac{2+4+6}{1+3+5} - \frac{1+3+5}{2+4+6}$$?

A. -1
B. 5/36
C. 7/12 --> correct: $$\frac{2+4+6}{1+3+5} - \frac{1+3+5}{2+4+6}$$ = $$\frac{12}{9} - \frac{9}{12}$$= $$\frac{4}{3} - \frac{3}{4}$$ = $$\frac{4^2 -3^2}{4*3}$$ = $$\frac{7}{12}$$
D. 147/60
E. 43/3

(2+4+6)/(1+3+5) =12/9 = 4/3 = 1.33
(1+3+5)/(2+4+6) = 9/12 = 3/4 = .75

So answer will be around 0.58. Only C is close so answer C
