That's the type of problem that you best type in a calculator.
This is represented as: 10 x 3000000 = 30000000
3000000 x 8077567 = 24232701000000
3000000 x 7 = 21000000
3000000 x 3
3000000 (Three million)
130 x 3 million = 390 million
3,000,000 multiplied by 100,000 is 300,000,000,000.
Simple. 3 x 107
2 x 3,000,000 = 6,000,000 six million
3000000 x 0.025 = 3000 x 25 = 75000
2.5% = 0.025 0.025 x 3,000,000 = 75,000
20% of 15000000 = 0.20 x 15000000 = 3000000
