I need help solving these:
A) 8500000 * 70.70 / 884452900
B) 447000 * 80.70 / 884452900
C) 227000 * 1090 / 884452900
Due to the large magnitudes, you may have trouble entering the numbers into your calculator. Also, doing the multiplication first may cause overflow.
Assuming you can enter the numbers as-is, divide the large values first, then multiply by the smaller number.
Or, you may just want to use scientific notation:
8500000 * 70.70 / 884452900
= 8.5*10^6 * 7.07*10^1 / 8.844*10^8
= 6.795*10^-1
= .6795
Use as many significant digits as you feel useful.
