Answer 2

Step-by-step explanation:

25860mg to kg

1mg =1/1000000 kg

25860 mg = 25860/1000000 = 0.025860 kg

128 paise to ruppees

1 paise = 1/100 rupees

128p=128/100 =1.28 rupees

3L and 725 ml to L

3l and 725ml =3000ml+725ml=3725ml

hence 3725ml to L

1ml=1/1000

3725ml=3725/1000=3.725L

47cm 20 mm to m

47cm 20mm =470+20=490 mm

490 mm to m

1mm=1/ 1000 m

490 mm=490 / 1000 =0.49 m

928 cm to km

1 cm=10000km

928cm=928/100000=0.00928 km
