80 as a Decimal

Professor Greenline Explaining Math Concepts

This is a straightforward question on decimal representation. Before diving into decimals, it's important to understand what they mean. Decimals are a way to represent numbers that are not whole, using a decimal point (.) to separate the whole number part from the fractional part. The numbers to the left of the decimal point represent the whole number, and those to the right represent the fractional part. In this case, the number 80 is a whole number.

Answer

80 as a decimal is simply written as 80.0. It is a terminating decimal, meaning it does not repeat and ends after a certain number of digits.

 

Explanation

To express 80 in decimal form, we simply acknowledge that it is already a whole number. By adding a decimal point followed by a zero, we indicate that there are no fractional parts.

 

Step 1: Identify that 80 is a whole number.

 

Step 2: Write 80 with a decimal point and a zero to show that there are no fractional parts, resulting in 80.0.

 

Step 3: Understand that this is a terminating decimal as it does not continue or repeat.
