Final answer:
10 kg is converted to 0.01 tonnes by dividing by 1000, and 9.8 kg is converted to 9800 grams by multiplying by 1000.
Step-by-step explanation:
Converting Units of Mass
To convert 10 kg into a tonne, we use the fact that 1 tonne is equal to 1000 kg. Therefore, to convert kilograms to tonnes, you divide the number of kilograms by 1000. For 10 kg, it is:
10 kg / 1000 = 0.01 tonnes.
To convert 9.8 kg into grams, we use the conversion that 1 kg is equal to 1000 grams. Multiplying 9.8 kg by 1000 gives:
9.8 kg x 1000 = 9800 grams.
