How would you round these numbers

[Gillian Gabrielsen2F]

How do you round numbers such as 7.956 and 4.9773 to two sigfigs? I normally round to 8.0 or 5.0 but that seems incorrect

[Sabina House 2A]

I believe that rounding those answers to 8.0 and 5.0 is correct if using two sig figs.

[Hannah Lechtzin 1K]

8.0 and 5.0 would be correct if you are rounding to two sig figs

[Brendan Duong 1I]

Recall you always round either up or down the last significant figure!

[Abby Lam 3F]

I think you are correct. The zero in that case counts as a sig fig.

[Inderpal Singh 2L]

8.0 and 5.0. Remember that any zero's at the end of a number after a decimal point count as a significant figure :)

[Alex Mele 2A]

Your numbers are correct! For more information about rounding and sig figs in general, the link on Dr. Lavelle's website is short and really helpful. https://lavelle.chem.ucla.edu/wp-conten ... OUT_SF.pdf

[Chinyere Okeke 2J]

The way you rounded it is correct. I also get nervous when rounding numbers with sigfigs like that. But you should remember to round only at the end when you have your answer because rounding in the intermediate steps could cause you to get the wrongs answer.

[Gicelle Rubin 1E]

You actually did it correctly!! I also had my doubts about my rounding at first.

[Dane_Beasley_1E]

Rounding those numbers to 8.0 and 5.0 would be correct. Zeroes following a number 1-9 count as a significant figure when there is a decimal.

Professor Lavelle has a really good lesson on sig figs on his website that really helped me!
