Perform calculations to the correct number of significant figures.
a. 3.10007 x 9.441 x 0.0301 /2.31
.8809596/2.31= .38136779
to round properly you take the quantity with the fewest significant figures which is 3 and round the fourth
=.381
b. Was the same problem as a, is the book messing with us?!
c. 2.5110 x 21.20 / (44.11+1.223)
53.2332/45.333 = 1.1742704
Since the addition problem only had 2 significant figures within the decimal (44.11) there will only be 2 significant figures.
=1.2
d. (12.01 x 0.3) + 4.811
3.603 + 4.811= 8.414
since .3 only had 1 significant figure the answer must be rounded to one significant figure
=8
