200000000000000 x 10 = 2000000000000000
2 x 10^11 x 2 x 10^11 = 4 x 10^22, or 40 sextillion
5% of 200 billion= 5% * 200000000000= 0.05 * 200000000000= 10,000,000,000 or 10 billion
Use scientific notation. 9 x 10^10 times 2 x 10^2 = 18 x 10^12 Eighteen trillion
500 billion times 10 is 5000000000
10% of 1 trillion = 100 billion.
It is then 75 billion
930 billion
the sum of 80 + 20 + 90 + 10 = 200
It is: 250,000,000,000 = 250 billion
