Answer:
Step-by-step explanation:
Since 10 mm = 1 cm
we can convert 47 mm as 47x1/10 = 4.7 cm.
----------------------------------------
SInce conversion factor for milligrams to grams is 1000 mg = 1 gram
we have
2900 mg = 2900/1000 = 2.9 gms.
-------------------------------------------
For conversion of m to cm we have conversion factors as
1 m = 100 cm.
Hence 7.2 m = 7.2x100 cm = 720 cm.
