The area of one jellyfish is pi r squared or 3.14 x 1 squared (the diameter of the jellyfish is 2 feet so the radius is 1 foot) or essentially 3.14 square feet. 2000 x 3.14 = 6280 square feet. The area of the ocean floor is 120 x 360 feet or 43200 square feet. So 6280/43200 is equal to 0.15 or 15%
4x + 6 + 5x + 3 = 90
9x +9 = 90
( Subtract 9 from 9 and 90 )
9x = 81
( Divide 9x and 81 by 9 )
x = 9

NO. To be a proportion, the have to get the same ratio, or the 1st fraction should equal the 2nd:
Is 3/4 =9/19? Certainly not, Hence it's not a ratio
