Vedclass · Answer

(C) To round a number to three decimal places, we look at the fourth decimal digit.If the digit to be dropped is $5$ and there are no non-zero digits following it, the preceding digit is left unchanged if it is even, and increased by $1$ if it is odd.For $17.0145$, the digit to be dropped is $5$ and the preceding digit is $4$ (even). So, it remains unchanged. The rounded number is $17.014$.For $21.0235$, the digit to be dropped is $5$ and the preceding digit is $3$ (odd). So, it is increased by $1$. The rounded number is $21.024$.Thus, the resulting numbers are $17.014$ and $21.024$.

The numbers $17.0145$ and $21.0235$ were rounded to three figures after the decimal point. The resulting numbers, respectively, are
