Understanding Percentages

Before diving into the conversion, let's briefly review what percentages are. A percentage represents a fraction of 100. For example, 50% means 50 out of 100, or 50/100. Converting a fraction to a percentage means expressing that fraction as a part of 100.

Calculating 57/80 as a Percentage

There are two main methods to convert 57/80 to a percentage:

Method 1: Using Decimal Conversion

2. Multiply by 100: Multiply the decimal result (0.7125) by 100. This equals 71.25.

3. Add the percentage symbol: Add the "%" symbol to indicate it's a percentage.

Therefore, 57/80 is equal to 71.25%.

Method 2: Direct Proportion

57/80 = x/100

To solve for 'x' (our percentage):

1. Cross-multiply: 57 * 100 = 80 * x This simplifies to 5700 = 80x

2. Solve for x: Divide both sides by 80: x = 5700 / 80 = 71.25

Therefore, once again, 57/80 equals 71.25%.
