Which expression will produce an answer with the fewest significant figures A 22.4 - 15.1 B 5070 - 3880 C 15.4 - 2.2 D 22.7 48.2?

To determine which expression produces an answer with the fewest significant figures, we need to consider the decimal places in each calculation.

• A: 22.4 (one decimal) - 15.1 (one decimal) = 7.3 (one decimal)
• B: 5070 (3 significant figures) - 3880 (3 significant figures) = 1190 (3 significant figures)
• C: 15.4 (one decimal) - 2.2 (one decimal) = 13.2 (one decimal)
• D: 22.7 (one decimal) + 48.2 (one decimal) = 70.9 (one decimal)

The expression with the fewest significant figures is A, which results in one decimal place.
