With my "science" hw everything relates to math ugh

1. 3.0 mL * (1 L )/((1000 mL) = 0.003 L

2. 0.24 dag * (10 g)/(1 dag) * (1000 mg)/(1 g) = 2,400.0 mg

3. 1350.0 mm * (1 m)/(1000 mm) = 1.35 m

4. 20.0 kg * (1000 g)/(1 kg) = 20,000.0 g

5. 0.4 cL * (1 L)/(100 cL) * (1 hL)/(100 L) = 0.00004 hL

6. 310.0 m * (1 km)/(1000 m) = 0.31 km

Why are u not just putting the numbers this is to much
