90% as a decimal

Professor Greenline Explaining Math Concepts

It is a simple question on decimal conversion. Firstly, we have to learn percentages and decimals. A percentage represents a part out of 100. In this case, 90% represents 90 out of 100. A decimal is a way to represent a number that is 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

90% in decimals can be written as 0.9.

Explanation

To convert 90% into a decimal, we divide by 100. This is because percent means per 100. So, 90% becomes 90/100. Simplifying this fraction, we get 0.9.

 

Let's see the step-by-step breakdown of the process:

 

Step 1: Identify the percentage, which is 90%.

 

Step 2: To convert to a decimal, divide the percentage by 100: 90 ÷ 100.

 

Step 3: This division gives us 0.9, which is the decimal representation of 90%.
