Approximately how many times greater is 1.2×103 than 4×10−1 ? 3 30 300 3000

D. 3000. Let your calculator do the work. Be careful how you enter this in. Write it like this.1.2 * 10^3 divided by 4 * 10^-1 Your calculator will do this nicely. The trick is the - 1. Put it in the calculator like this.1.2 *10^3=÷4*10^(-1) = The calculator should read 3000. That's one way to do it. Another way is just to do it all by hand. The numbers are easy enough. 1.2 * 10^3 means shift the decimal 3 places right. 1 200 which is 12004 * 10^-1 can be handled 2 ways 10 to the minus 1 in the denominator becomes 10^1 in the numerator. 1200 * 10^1 12000 Now you are still left with 4 in the denominator.12000/4 = 3000. Hope this helps :) 

The answer can be gotten by saying 1200/0.4 which gives 3000
