In multiplication, the result should have the same number of significant figures as the factor with the fewest significant figures.

Step2: Analyze Part A

45.0254 has 6 significant figures and 89.00205 has 7 significant figures. The product 45.0254×89.00205 = 4007.3528577 is rounded to 6 significant figures, which is 4007.35.

Step3: Analyze Part B

0.00740 has 3 significant figures and 46.5901 has 6 significant figures. The product 0.00740×46.5901 = 0.34476674 is rounded to 3 significant figures, which is 0.345.

Step4: Analyze Part C

45857 has 5 significant figures and 904875 has 6 significant figures. The quotient 45857÷904875 = 0.05067776 is rounded to 4 significant figures, which is 0.05068.
