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.
