. Report the correct number of significant figures.
a. 87.3 + 0.001 =
b. 0.201 + 0.92 =
c. 320 + 8.41 =
d. 1200 – 60 =

Explanation:

Solving (a): 87.3 + 0.001 =

87.3 --> 3 significant figures

0.001 --> 1 significant figure

So, the answer must be in at least 3 significant figures

Solving (b): 0.201 + 0.92 =

0.201 --> 3 significant figures

0.92 --> 2 significant figures

So, the answer must be in at least 3 significant figures

Solving (c): 320 + 8.41 =

320 --> 2 significant figures

8.41 --> 3 significant figures

So, the answer must be in at least 3 significant figures

Solving (d): 1200 – 60 =

1200 --> 2 significant figures

60 --> 1 significant figure

So, the answer must be in at least 2 significant figures
