carry out each calculation and give the answers using the proper number of significant figures.
part 1 of 2
10.00×2.8=
part 2 of 2
\frac{0.808}{26348}=

Explanation:

Step1: Multiply for Part 1

$10.00\times2.8 = 28.00$. Since 2.8 has two - significant figures, the answer should be rounded to two - significant figures, so it is 28.

Step2: Divide for Part 2

$\frac{0.808}{26348}=0.000030664642$. The number 0.808 has three significant figures. Rounding 0.000030664642 to three significant figures gives 0.0000307.

Answer:

Part 1: 28
Part 2: 0.0000307
