Question

Sixty three thousandth is equal to
(A) $ 0.63 $
(B) $ 0.603 $
(c) $ 0.063 $
(D) $ 0.630 $

Answer 1

Hint: One thousandth is $ {1000^{th}} $ part of $ 1 $ . That means one thousandth is equal to $ \dfrac{1}{{1000}} $ .
So we can get sixty three thousandth by dividing sixty three by 1000.

Complete step-by-step answer:
In algebra, a decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point. The dot in a decimal number is called a decimal point. The digits following the decimal point show a value smaller than one.
One thousandth is equal to $ \dfrac{1}{{1000}} $
In the same way, sixty three thousandth is $ {1000^{th}} $ part of $ 63 $ .
We will get that by dividing $ 63 $ by $ 1000 $
Therefore, sixty three thousandth $ = \dfrac{{63}}{{1000}} $
 $ = 0.063 $
Therefore, from the above explanation, the correct answer is, option (c) $ 0.063 $
So, the correct answer is “Option C”.

Note: The third decimal decimal digit from the decimal point is the thousandth digit. In case of 63. After dividing it by $ 1000 $ , we get $ 0.063 $ where $ 0 $ is the tenth, $ 6 $ is the hundredth and $ 3 $ is the thousandth digit in it.
