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

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