Answer:  A)  2/3 is shaded.     B) 66.67%  is shaded.

Step-by-step explanation:

The whole big triangle holds  9 total triangles in it.

Out of the 9  triangles  6 of them are shaded so  the fraction will be 6/9  which reduces to 2/3.  

Now convert 2/3 to a decimal to find what percentage is shaded.

2/3 = 0.6666...  

0.6666 * 100 = 66.666..

66.666  as a percent  is 66.67%
