rate = (20000000 divided by 30000000) multiplied by 100% = 66.67%
thirty million
20000000 x 20 = 400000000
30000000
30000000000000
200000000 x 20000000 = 4,000,000,000,000,000 (4 quadrillion)
30000000 -30000000 = 0
200,000,000,000,000
3,000,000,000
This is represented as: 10 x 3000000 = 30000000
3 x 10^7
the answer is 2000000000000.
