Remark
Some calculators will give you the answer directly without any intermediate steps. Just a b/c key and the * key. Having done that the answer is 2/17
Solution
Doing this by hand can be a bit of trouble. I think the easiest way is to multiply the first and third together and then worry about the middle one.

now just multiply your answer from the above job with the middle fraction.

because 12 ÷ 6 = 2
