The Correct Answer and Explanation is:
0.109
To convert 109 grams to kilograms, you need to understand the fundamental relationship between these two metric units of mass. The prefix “kilo” in kilogram signifies one thousand, which means that 1 kilogram is exactly equal to 1,000 grams. This conversion factor is the key to solving the problem.
When you are converting from a smaller unit (grams) to a larger unit (kilograms), you must divide the given number of grams by 1,000. This is because you are determining how many sets of 1,000 grams can be made from your initial amount.
The calculation for this specific conversion is as follows:
109 grams ÷ 1,000 = 0.109 kilograms
A simple way to divide by 1,000 is to move the decimal point three places to the left. For the whole number 109, the decimal point is understood to be at the end (109.0). Moving the decimal three places to the left gives you 0.109.
Therefore, 109 grams is equivalent to 0.109 kilograms. This conversion is a common and practical skill, particularly in science, cooking, and international commerce, where the kilogram is a standard unit of measurement for mass. By remembering that there are 1,000 grams in a kilogram, you can easily perform this type of conversion by dividing the gram value by 1,000.
