Answer:

1.) 38 m = 0.038km

Solution

Convertion

1m =0.001km

38mx0.001km =0.038 km

2.) 5 g =5000 mg

Solution

Convertion

1 g=1000mg

5 gx 1000mg =5000mg

3.) 875 mg =0.875g

Solution

Convertion

1mg =0.001g

875 mg x 0.001g=0.875

4.) 15 kg = 15000g

Solution

Convertion

1 kg =1000g

15kg x 1000g=15000

5.) 25000 mg = 25g

Solution

Convertion

1mg =0.001g

25000mg x 0.001g=25

6.) 85 cg = 850mg

Solution

Convertion

1cg =10 mg

85cg x10 mg =850 mh
