USING SIGNIFICANT FIGURES TO SHOW THE RELIABILITY OF DATA

Round 0.0645 g to 2 significant figures:

0.065 g

Round 0.0952 km to 2 significant figures:

0.095 km

Multiply and round to the proper number of significant figures. (0.234 cm)(3.53 cm) =

0.826

Pick the TWO conversions which are exact. 1 yd = 36 in 454 g = 1 lb 1 kg = 1000 g 1 kg = 2.204 lb

1 yd = 36 in 1 kg = 1000 g

Multiply and round to the proper number of significant figures. (896.5 cm)(12 cm) =

11,000

Give the number of significant figures: 0.011 cm
