1. How many kilograms are equal to 1500 centigrams?

2. Determine the number of liters in 6578 milliliters?

3. How many decimeters are equivalent to 0.45 kilometers?

This is something you need to get a handle on. What's the problem? Are you just wanting someone to do your work or is there something you don't understand? Explain please.

To convert between different units of measurement, particularly when dealing with different metric prefixes, you can use conversion factors. Conversion factors are ratios that relate the two units you want to convert between. Here's how you can calculate the answers to the given questions:

1. To convert centigrams to kilograms, we can use the conversion factor that 1 kilogram is equal to 100,000 centigrams.

Therefore, to convert 1500 centigrams to kilograms, we divide 1500 by 100,000:

1500 centigrams ÷ 100,000 = 0.015 kilograms

So, 1500 centigrams is equal to 0.015 kilograms.

2. To convert milliliters to liters, we can use the conversion factor that 1 liter is equal to 1000 milliliters.

Therefore, to convert 6578 milliliters to liters, we divide 6578 by 1000:

6578 milliliters ÷ 1000 = 6.578 liters

So, 6578 milliliters is equal to 6.578 liters.

3. To convert kilometers to decimeters, we can use the conversion factor that 1 kilometer is equal to 10,000 decimeters.

Therefore, to convert 0.45 kilometers to decimeters, we multiply 0.45 by 10,000:

0.45 kilometers × 10,000 = 4500 decimeters

So, 0.45 kilometers is equal to 4500 decimeters.
