- 164,000,000,000 in scientific notation is 1.64 x 10
^{11}(we needed to move the decimal 11 places to the left) - To figure out how many football fields we need, we simply divide 1.64x10
^{11}by 1.20x10^{2} - To divide, we can do the numerical part 1.64/1.2 separately for 1.37 (rounded), and also divide the 10
^{11}/10^{2}separately for 10^{9}(we get the 9 from 11-2). **So your answer is 1.37x10**^{9}, or 1,370,000,000
