प्रश्न
Without actual division, show that each of the following rational numbers is a terminating decimal. Express each in decimal form.
(i) `17 /320`
उत्तर
`17/320 = 17/(2^6 × 5) = (17 × 5^5)/(2^6 × 5^6) = 53125/1000000 = 0.053125`
We know either 2 or 5 is not a factor of 17, so it is in its simplest form.
Moreover, it is in the form of (2m × 5n).
Hence, the given rational is terminating.
