Introduction

In mathematics, expressing length in decimals is a crucial concept that helps us understand and work with measurements in various units. In this article, we will explore how to express a length of 328 meters 50 centimeters in decimal form, and then convert it to millimeters.

Understanding the Units

Before we dive into the conversion process, let's understand the units involved:

Meter (m): The base unit of length in the International System of Units (SI).
Centimeter (cm): A unit of length that is equal to one-hundredth of a meter.
Millimeter (mm): A unit of length that is equal to one-thousandth of a meter.

Expressing 328 Meters 50 Centimeters in Decimal Form

To express 328 meters 50 centimeters in decimal form, we need to convert both the meters and centimeters to a single unit, which is meters.

Converting Centimeters to Meters

Since there are 100 centimeters in a meter, we can convert 50 centimeters to meters by dividing by 100:

50 cm ÷ 100 = 0.5 m

Adding the Meters

Now that we have converted the centimeters to meters, we can add the meters:

328 m + 0.5 m = 328.5 m

Converting Meters to Millimeters

To convert meters to millimeters, we need to multiply by 1000, since there are 1000 millimeters in a meter:

328.5 m × 1000 = 328,500 mm

Conclusion

In this article, we have learned how to express a length of 328 meters 50 centimeters in decimal form, and then convert it to millimeters. By understanding the units involved and using the conversion factors, we can easily perform these conversions.

Key Takeaways

To express a length in decimal form, we need to convert all units to a single unit.
