100 as a decimal is simply 100.0. In decimal notation, whole numbers are typically written without a decimal point, but adding a decimal point and a zero does not change the value. For example, 100 is the same as 100.0 in decimal form.
Here’s a brief explanation:
- Whole numbers like 100 are already in decimal form.
- Adding a decimal point and a zero (100.0) does not alter the value; it remains 100.
- This notation is often used to indicate precision in measurements or calculations.
So, whether you write 100 or 100.0, both represent the same value in decimal form.
