To convert 45 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 look like this: 1 meter / 100 centimeters = x meters / 45 centimeters.
3. Cross multiply to solve for x: 100x = 45. Divide both sides by 100 to find the value of x: x = 0.45 meters.
Therefore, 45 cm is equal to 0.45 meters.
Real-life example: If you have a piece of fabric that measures 45 cm in length and you want to know how many meters that is, you would use the conversion factor of 1 meter = 100 cm to find that the fabric is 0.45 meters long.
