प्रश्न
Without actual division, show that each of the following rational numbers is a terminating decimal. Express each in decimal form.
(i) `171/800`
उत्तर
`171/800 = 171/(2^5 × 5^2 )= (171 × 5^3)/(2^5 × 5^5) = 21375/100000 = 0.21375`
We know either 2 or 5 is not a factor of 171, so it is in its simplest form.
Moreover, it is in the form of (2m × 5n).
Hence, the given rational is terminating.
