In the west region of the US, the ratio of densely vegetated land to sparsely vegetated land is 11:18. In the central region of the US, the ratio is 3:1. What is the difference in percentage of densely vegetated land from the west region to the central region?
What is 37.1%?
to solve:
know.. percentage = part/total x 100%
after plugging.. 37.9%
then, knowing 75% is central.. 75%-37.9% = 37.1%
