How many digits after the decimal point will appear in the decimal expansion of (\frac{7}{1250}) in lowest form?

Advertisement

Answer and explanation

Correct answer: (4)

Step 1: (1250=2\cdot 5^4), and the fraction is already in lowest form. Step 2: The powers of (2) and (5) are (1) and (4), so the decimal has (4) places. Step 3: Use the larger exponent to find the terminating decimal length quickly.
