Answer:
Step-by-step explanation:
We convert into decimals and then multiply
Otherwise we can convert everything into one unit and then multiply.
10 hg = 1 kg and 100x1000 cg = 1kg
Using this
a. 9 kg 3 hg 1 cg × 9 = 9.300001x9=83.700009 kg
b. 11 dg 4 cg × 12 = 11.400004x12 =16.8000048kg
c. 10 g 5 dg × 6 = 10.5x6 =63.0 kg
d. 5 g 3 dg 4 cg × 8 =5.300004x8 = 42.400032
