Evaluate the Fraction (Please see screenshot) 

Evaluate the fraction. (6.38 × 104) (5.15 × 106) 2.51 x 108 1.31 Incorrect < Feedback Macmillan Learning Although you can simply enter the numbers in your calculator and let the calculator do the work, some calculators can be confusing in the way that exponential numbers are entered. It is always good to do a mental check in your head, estimating the order of magnitude of the answer, to make sure you have not made a mistake in entering the numbers. In evaluating the fraction, treat the coefficients and the powers of 10 separately at first. Remember to add exponents when multiplying and to subtract exponents when dividing.
