Answer:
1500 mg is the least mass
Step-by-step explanation:
Lets convert them all to the same mass unit,
1500 mg to grams: 1500 mg / 1000 = 1.5 grams
13.2 kg to grams: 13.2 kg x 1000 = 13,200 grams
30000 cg to grams: 30,000 cg / 100 = 300 grams
7428g no conversion needed!
1.5 grams, 13,200 grams, 300 grams, 7,428 grams
1.5 is the smallest number
