Select all correctly rounded results, using the rules of significant figures.

Answer:

A, B, C

Solution:

$703 + 7 + 0.66 = 710.66 \to 711$ (units place).

$2.21 \times 0.3 = 0.663 \to 0.7$ (one significant figure).

$12.4 \times 84 = 1041.6 \to 1.0 \times 1 0^{3}$ (two significant figures).

$\frac{14.28}{0.714} = 20.0$ (three significant figures), not $20.00$ .
