Answer:
(c) 3 unshaded to 1 shaded
Step-by-step explanation:
If your description of the diagram is correct that there are 12 unshaded and 4 shaded triangles, then the desired ratio is ...
unshaded : shaded = (12 unshaded) : (4 shaded) = 12 : 4 = 3 : 1
__
The ratio is reduced to lowest terms by dividing both numbers by the greatest common factor, 4. The order of parts of the ratio needs to match the requested order: unshaded to shaded. The given numbers are in reverse order, requiring that you actually read and understand the question.
