Answer:
Hello! Your answer is 1/2
Explanation:
there are six cubes and three of them are shaded. That is half of the parallelograms.
So 1/4 wouldn't make sense because there are three shaded out of six.
1/6 doesn't make sense because since there is six in total for it to be 1/6 there needs to be 1 shaded out of six.
And finally 1/3 doesn't make sense because 1/3 would have to be two out of six shaded.
Have a wonderful day/night/afternoon and good luck my friend!
