I need help solving these:

Question

A) 8500000 * 70.70 / 884452900

B) 447000 * 80.70 / 884452900

C) 227000 * 1090 / 884452900

Answer 1

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.
