Question

1.     Perform the operations and write the answers in scientific notation with the appropriate number of significant digits:

a.     27.39 x 0.0320 =                                                                    

b.     62.304/2.93 =                                                                         

c.      0.032 + 12.19 =                                                                      

d.     (7.30 – 5.1)/12.083 =                                                             

e.     (39.04 + 16.317)/(0.0341 + 0.207) =                                     

Explanation / Answer

With multiplication/division processes we carry as many significant figures as the one with the least. a. 27.39*0.0320 = 0.8764 = 0.876 The 0.0320 term has 3 significant figures: 3,2 and 0. b. 62.304/2.93 = 21.26=21.3 c. For addition and subtraction, we examine the least amount of significant digit decimal places. 0.032+12.19 = 12.222=12.22 d. 7.30-5.1 = 2.20/12.083 = 0.182=0.18 e. =0.2411=0.241
