Question - Conversion and Division of Metric Units

For part (a), we first convert 2.1 kg to grams since there are 1000 grams in a kilogram.

2.1 kg = 2.1 \times 1000 g = 2100 g

Now we divide 330 g by 2100 g.

\frac{330 g}{2100 g} = \frac{330}{2100} = \frac{1}{2100/330} = \frac{1}{6.36363636} \approx 0.157

The approximate answer for part (a) is 0.157.
