To convert 30 cm to a different unit, such as meters, you can use the following steps:
1. Identify the conversion factor between the two units. In this case, 1 meter is equal to 100 centimeters.
2. Set up a proportion to convert the value. Since we want to convert from centimeters to meters, the proportion will be: 1 meter = 100 centimeters.
3. Cross multiply to solve for the unknown value. In this case, we have: 30 cm * 1 meter = x meters * 100 cm. Simplifying this equation, we get: 30 cm = x meters * 100 cm.
4. Divide both sides by 100 cm to solve for x. x = 30 cm / 100 cm = 0.3 meters.
Therefore, 30 cm is equal to 0.3 meters.
Real-life example: If you have a piece of fabric that measures 30 cm in length, you can convert this measurement to meters to better understand its size. By converting 30 cm to 0.3 meters, you can visualize that the fabric is approximately one-third of a meter long.
