90 as a Decimal

Professor Greenline Explaining Math Concepts

This is a simple question about decimal representation. To understand this, we need to learn about whole numbers and decimals. A whole number is a complete entity without any fractional or decimal component. A decimal, on the other hand, is a way to represent numbers that are not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole part, and those to the right represent the fractional part.

90 as a decimal

 

Answer

 

90 as a decimal is written as 90.0. This is because 90 is a whole number, and when expressed as a decimal, it remains the same, with a zero in the fractional part.

 

Explanation

 

To express 90 as a decimal, we simply need to understand that it is already a whole number. Thus, when written in decimal form, it includes a decimal point followed by a zero, indicating there are no fractional parts.

 

Step 1: Recognize that 90 is a whole number.

 

Step 2: Write 90 with a decimal point by adding ".0" to it, which does not change its value.

 

Step 3: The result is 90.0, showing that it is a whole number with no fractional component.
