Model Answer & Options
Source: Extra Practice1040
1039.78
1039.8
1000
Explanation
In multiplication and division, the result should have the same number of significant figures as the term with the least significant figures. 25.2 has 3, 1374 has 4, and 33.3 has 3. The result must have 3 significant figures. Calculation: 1039.78... Rounding to 3 sig figs gives 1040 (The zero is not significant unless specified). 1039.78 and 1039.8 have too many sig figs. 1000 has only 1 sig fig.
