As we know.

1 kg = 1000 g 

which means 

1 g = \frac{1}{1000}kg

So,

(a) 2 g

     2 g = \frac{2}{1000}kg=0.002kg   

(b) 100 g         

     100 g = \frac{100}{1000}kg=0.1kg

(c) 3750 g

    3750 g = \frac{3750}{1000}kg=3.75kg
            

(d) 5 kg 8 g  

  5kg\:\:8g=5+8g =5kg+ \frac{8}{1000}kg=5kg+0.008kg=5.008kg      

(e) 26 kg 50 g

26kg\:\:50g=26+50g =26kg+ \frac{50}{1000}kg=26kg+0.05kg=26.05kg
