Sig fig simple question

Postby Jacob Samuels 1E » Mon Apr 09, 2018 12:24 pm

Is this a correct use of sig figs?
1 x 0.9342769 = 0.9
You are supposed to keep the lowest number of sig figs from your problem, and since "1" has just 1 sig fig, you keep only the 0.9 right?

In this case, if the decimal was .985243649 but you only wanted one significant figure would you round up to 1? Or would you stay at .9

Should 1 be written as "1." or does that not matter?

If you only want 1 sig fig then you would round up to 1.
You don't have to put a decimal after the 1 because it is one sig fig without it but you can put it if you want to.
Hope this helps

Yes, when multiplying and dividing in a problem, you round to the least number of significant figures in the problem. In addition and subtraction, you round to the least number of decimals in the problem.
