Use the propotion to convert millimeters to centimeters.
10mm = 47mm

1 cm x

a) x = 0.47 cm
b) x = 4.7 cm
c)x = 47 cm
d)x = 470 cm

use the proportion to convert milligrams to grams.
1,000 mg = 2,900 mg

1m 7.2m
a) x = 0.72 cm
b) x = 7.2 cm
c) x = 72 cm
d) x = 720 cm

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.

x = 25/2304
