3 as a Decimal

Professor Greenline Explaining Math Concepts

Converting whole numbers to decimals is straightforward. A whole number like 3 can be easily expressed as a decimal. A decimal is a numerical representation that uses a point (.) to separate the whole part from the fractional part. However, when dealing with whole numbers, there are no fractional parts, but we can still express them in decimal form for consistency or clarity in certain mathematical operations.

Step 1: Start with the whole number 3.
