4mm as a Decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn about units and decimals. A unit represents a specific measurement, and in this context, it is millimeters. There are different ways to represent numbers, and decimals are one of them. A decimal is a way to represent numbers that are not whole, using a (.) or a decimal point to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.

Answer

4mm in decimals can be written as 0.004m. This conversion shows the relationship between millimeters and meters.

 

Explanation

To convert 4mm into a decimal representing meters, we use the conversion factor between millimeters and meters. There are 1000 millimeters in a meter. Let's see the step-by-step breakdown of the process:

 

Step 1: Recognize that 1 meter equals 1000 millimeters.

 

Step 2: Set up the conversion factor: 1mm = 0.001m.

 

Step 3: Multiply 4mm by the conversion factor: 4mm × 0.001m/mm = 0.004m.

 

Thus, 4mm is equal to 0.004 meters in decimal form.
