GDP= $69.97*10^12=$7.00×1013
Population = 6,973,738,433=7,00,00,00,000=7*10^9
Approx global GDP per person=( 70*10^12)/(7*10^9)=10*1000=10,000$ per person approx
Answer: D
Population = 6,973,738,433=7,00,00,00,000=7*10^9
Approx global GDP per person=( 70*10^12)/(7*10^9)=10*1000=10,000$ per person approx

This problem is asking you to divide $69.97 trillion by 6,973,738,433. When dealing with numbers that have many zeros, you can avoid mistakes by using scientific notation or by writing out the numbers and canceling zeros before using the calculator.
Before doing that, however, look at the answers—they are very far apart from one another, which gives you license to estimate. GDP is about 70 trillion. Population is about 7 billion. Thus:
Answer: D
