What would the ratio of unshaded parts to total parts be if four are shaded and three are not shaded
The ratio of unshaded parts to total parts would be 3:7.
This is because there are a total of 7 parts (4 shaded + 3 unshaded), and out of those 7 parts, 3 are unshaded.
So the ratio is 3 unshaded parts : 7 total parts or 3:7.
