A fraction p/q is in lowest terms and q = 2³ × 5². What can you say about its decimal form?

Question

Accepted Answer

It terminates after 3 decimal places. q = 200 has only the primes 2 and 5, so the decimal terminates. Multiplying by 5 gives 2³ × 5³ = 1000, so 3 decimal places are needed (for example 1/200 = 0.005).
