- Divide the numerator by the denominator. In this case, divide 5 by 7.
- Multiply the result by 100 to convert it to a percentage.
Let's break down the steps:
- Divide 5 by 7: 5 ÷ 7 = 0.7142857142857143
- Multiply the result by 100: 0.7142857142857143 × 100 = 71.42857142857143%
Therefore, 5/7 as a percentage is approximately 71.43%.
