Converting fractions to percentages is a common mathematical operation that can be useful in various aspects of life, including finance, education, and science. One such conversion is turning the fraction 9/4 into a percentage. In this article, we will walk through the steps to easily convert 9/4 to a percentage and provide a clear explanation of the process.
Understanding Fractions and Percentages
Before diving into the conversion, it’s essential to understand what fractions and percentages represent. A fraction is a way to express a part of a whole as a ratio of two numbers, separated by a slash. In the case of 9⁄4, it means 9 parts out of a total of 4 parts. On the other hand, a percentage is a way to express a value as a proportion of 100. It’s often denoted by the symbol “%”.
Converting 9⁄4 to a Decimal
The first step in converting 9⁄4 to a percentage is to convert it to a decimal. To do this, we divide the numerator (9) by the denominator (4).
| Operation | Result |
|---|---|
| 9 ÷ 4 | 2.25 |
The result of this division is 2.25, which is the decimal equivalent of the fraction 9/4.
Converting the Decimal to a Percentage
Now that we have the decimal equivalent of 9⁄4, we can easily convert it to a percentage. To convert a decimal to a percentage, we multiply the decimal by 100 and add the percentage symbol.
| Operation | Result |
|---|---|
| 2.25 × 100 | 225% |
Therefore, 9/4 as a percentage is 225%.
