To simplify 12/18, you can see that the greatest common factor is 6 (6 × 2 = 12, 3 × 6 = 18), and so you can divide by 6 to get D. 2/3 as your answer.
I'm pretty sure you could just select the answer to not show your working :)
I hope this helps!

Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
