Police entrance exam question

Answer 1

Your first step with anything like this should be rewriting things in a couple of ways to see if any of them make the pattern more obvious. Ie:

64/64 = 1

9/12 = 3/4 = 0.75

6/12 = 1/2 = 0.5

Can you see it now?

Answer 2

Try simplifying the fractions…

1, 3/4, 1/2

What’s the pattern? We’re subtracting 1/4 each time, so the next number in the sequence ought to be B. 1/4
