69300/(10^5 - 10^3) = 69300/(10(100^2-10^2))
=69300/((10)(100+10)(100-10))
=69300/(10*110*90)
=693/(9*11*10)
=77/(11*10)
=7/10
=0.7

The answer is therefore B.

Right off the bat, we can eliminate D and E, since we see the solution must be <1 (69300/99000). If we get stuck on test day, we'll have much better odds of guessing the right answer.

Now, we have:
69300 / 99000
693 / 990
* Note, these are both multiples of 9
77 / 110
* Both multiples of 11
7 / 10

Answer B

Competition Mode Question



\(\frac{69,300}{10^5 - 10^3} =\)

A. 0.693
B. 0.7
C. 0.71
D. 6.93
E. 7.1

Simplifying, we have:

69,300/[10^3(10^2 - 1)]

693/(10 x 99)

77/(10 x 11) = 7/10 = 0.7

Answer: B
