Question

Use proportions to convert 3,000 meters to kilometers.

A. 3 kilometers
B. 3.5 kilometers
C. 30 kilometers
D. 300 kilometers

Answer 1

To convert 3,000 meters to kilometers, divide the number of meters by 1,000 to get 3 kilometers. Hence, 3,000 meters is equal to 3 kilometers (option A).

Step-by-step explanation:

To convert 3,000 meters to kilometers, we need to understand that 1 kilometer (km) is equal to 1,000 meters (m). The task at hand requires converting from a smaller unit (meters) to a larger unit (kilometers), which means we need to divide the number of meters by 1,000.

Here is the step-by-step proportion approach to solve the conversion:

1. Write the unit conversion as a fraction or ratio: 1 km / 1,000 m = x km / 3,000 m.
2. Cross multiply to find the unknown value x: 1 * 3,000 = x * 1,000.
3. Solve for x: x = 3,000 / 1,000.
4. Calculate x to get the answer in kilometers: x = 3.

So, 3,000 meters equals 3 kilometers, which matches option A.
