Final answer:
To convert kg to grams, multiply by 1000. If 4 kg is 500 g, 1 kg is 125 g. To convert kg to pounds, multiply by 2.20462. To convert kg to milligrams, multiply by 1,000,000.
Step-by-step explanation:
To convert kg to grams, you need to multiply the number of kilograms by 1000. So, for part a, you would multiply 7.345 kg by 1000 to get 7345 grams.
To find out how many grams are in 1 kg, you can use the information given in part b. If 4 kg is equal to 500 g, then 1 kg would be equal to 500/4 = 125 grams.
To convert kg to pounds, you need to multiply the number of kilograms by 2.20462. So, in part c, you would multiply 6.35 kg by 2.20462 to get approximately 13.998 pounds. Finally, to convert kg to milligrams, you need to multiply the number of kilograms by 1,000,000. So, for part d, you would multiply 9.005 kg by 1,000,000 to get 9,005,000 milligrams.
