Options:
Answer:
C
Solution:
a + b = 0.92 + 0.08 = 1.00 (3 significant figures)
a - b = 0.92 - 0.08 = 0.84 (2 significant figures)
a × b = 0.92 × 0.08 = 0.0736 ≈ 0.07 (1 significant figure, limited by 0.08)
a / b = 0.92 / 0.08 = 11.5 ≈ 10 (1 significant figure, limited by 0.08)
Therefore, the number of significant figures are 3, 2, 1, and 1 respectively.
