has 3 significant figures but is precise to the thousandths place.2.
has 4 significant figures and is precise to the hundredths place.3.
has 2 significant figures and is precise to the hundredths place.When adding numbers, the result should be reported with the same number of decimal places as the measurement with the least number of decimal places. In this case, both
and
are precise to the hundredths place, which is less precise than the thousandths place of
.Now, let's perform the addition:
Since the least precise measurement is to the hundredths place, we round the result to the hundredths place:
Therefore, the sum is
.
