   Yellow and green contrast more than red and white ... (b) L/D ratios of greater than 4 to 1.

Explanation:

The answer is 3

Explanation: The contrast ratio is the ratio of the brightness of two colors used for the text and the background. For instance, if you used the gray-80 on a background with the color of the gray-20, divide 80 by 20, which is 4. The contrast ratio is 4 to 1.

So 90 divided by 30 is 3...
