Yes, here's a screenshot of it. For official practice exams, should I post screenshots as a spoiler when making a post?

Which of the following is equal to the ratio of 5 to 4?

A. \( \frac{ (0.8)^3}{(0.8)^4 } \)

B. \( \frac{ 5^2}{4^2 } \)

C. \( \frac{ 4}{5 } \)

D. \( \frac{ (2)(5)}{2^4 } \)

E. \( \frac{ 1.25}{0.4 } \)
Is this question from the GMAT Prep Focus mocks? Could you please share a screenshot? That would be very helpful. Thank you!

.8^3 / .8^4 can be written as 1 / (.8^4 /.8^3) = 1/ .8 = 10/8 = 5/4
