Converting fractions to percentages is a fundamental skill in mathematics, and it's essential for everyday calculations, finance, and more. In this article, we'll focus on converting 5/7 to a percentage in simple steps.
Understanding Fractions and Percentages
Before we dive into the conversion process, let's quickly review what fractions and percentages represent. A fraction is a way to express a part of a whole, with the top number (numerator) representing the part and the bottom number (denominator) representing the whole. A percentage, on the other hand, represents a proportion of a whole as a fraction of 100.
Step 1: Divide the Numerator by the Denominator
To convert 5/7 to a percentage, start by dividing the numerator (5) by the denominator (7).
Perform the division: 5 ÷ 7 = 0.71428571
Step 2: Multiply by 100
To convert the decimal to a percentage, multiply the result by 100.
Multiply 0.71428571 by 100: 0.71428571 × 100 = 71.428571%
Step 3: Round the Percentage (Optional)
Depending on your needs, you may want to round the percentage to a specific decimal place. For example, you can round 71.428571% to 71.43%.
Step 4: Express the Percentage with a Percent Sign
Finally, express the result with a percent sign (%).
The result is 71.43% (or 71.428571% if you prefer a more precise answer).
Step 5: Verify the Calculation (Optional)
To ensure the accuracy of your calculation, you can verify it by converting the percentage back to a fraction.
To do this, divide the percentage by 100 and simplify the fraction. You should arrive back at the original fraction, 5/7.
