Final answer:
To solve the calculation (1.39 x 10^-2) (0.043) / 0.07 with the correct number of significant figures, multiply (1.39 x 10^-2) by 0.043, then divide the result by 0.07. Round the final answer to three significant figures.
Step-by-step explanation:
To solve the calculation (1.39 x 10-2) (0.043) / 0.07 with the correct number of significant figures, we need to first perform the multiplication and then divide the result by 0.07:
(1.39 x 10-2) (0.043) = 0.059877
0.059877 / 0.07 = 0.85539
Rounding the answer to three significant figures gives us a final result of 0.855.
