I keep getting this wrong, and I'm not sure why. If someone can double check my work and let me know where I went wrong, thanks!
Chapter 02 Homework Rounding Off Numerical Values Resources previous l 6 of 17 l next Part B Drag the answers that have been comectly rounded to the appropriate number of significant figures to their place in the table. To avoid rounding errors, start with the unrounded value before conducting each manipulation. Drag the appropriate labels to their respective targets. 12.4. 13 12.47 Unrounded Answer Significant Figures Si 7.96 14.93 E246 15.0 3.7 14.9 3.63 14 3,623 7.966 help Submit Hints Answers Give Up Review PartExplanation / Answer
1)
Number - 12.462
Rounded to four significant figures - 12.46 (the last digit of this number is 2, which is <5, so no rounding it off)
Rounded to three significant figures - 12.5 (as 6 in 12.46 is greater than 5, we will increase the thenth place by one digit, thus rounding off to 3 places. the number becomes 12.5)
Rounded to two significant figures - 13 ( as the decimal place has a 5, we can round the number to the nearest whole number, hence 13)
2)
Number - 7.9652
Rounded to four significant figures - 7.965 (2 is less than 5, so no rounding off)
Rounded to three significant figures - 7.97 (as 5 is the last digit, so rounding the number we get,7.97)
Rounded to two significant figures - 8.0 ( rounding the decimal places, we get 8 as the whole number, and a zero after decimal point is considered in counting the number of significant figures.
3)
Number - 3.6225
Rounded to four significant figures - 3.623 (5 at the end, so no rounding off 2 to 3)
Rounded to three significant figures - 3.62 (as 3 is the last digit, so no rounding the number)
Rounded to two significant figures - 3.6 (as 2 is the last digit, so no rounding the number).
4)
Number - 14.925
Rounded to four significant figures - 14.93 (5 at the end, so no rounding off 2 to 3)
Rounded to three significant figures - 14.9 (as 3 is the last digit, so no rounding the number)
Rounded to two significant figures - 15 (as 2 is the last digit, so no rounding the number).
