Question 2 times 1/2 time 6/11 - Multiplying fractions

2 times 1/2 time 6/11 (fractions) the result is supposed to be 6/11 right?

On the test however the only options I have are:

12/11

15/11

67/22

15/2

I don't get it... Would there be an error on the test?

I would first convert the mixed number to an improper fraction, so that the product becomes:

$\displaystyle \frac{5}{2}\cdot\frac{6}{11}= \frac{5}{\cancel{2}}\cdot\frac{\cancel{2}\cdot3}{1 1}= \frac{15}{11}$

$\displaystyle 2\frac{1}{2}\,=\,\frac{5}{2}\,\neq\,1$

2 + 1/2 = 5/2

2 * 1/2 = 1

What am I missing?

I need to get my eyes checked...LOL! For some reason I read this originally as 2 1/2 * 6/11.

I am on my way to the corner...

Well, a minute will do...
15/11 is one of choices; OP probably has a typo;
probably should be (2 plus 1/2) or 2 1/2 times 6/11
