To convert a fraction to a percentage, you multiply the fraction by 100. In this case, we have the fraction 4 out of 5, which can be expressed as:
4 out of 5 as a fraction: 4/5
Now, let’s perform the calculation:
- Divide the numerator by the denominator: 4 ÷ 5 = 0.8
- Multiply the result by 100: 0.8 × 100 = 80
Therefore, 4 out of 5 is equivalent to 80%.
This means that if you have 5 parts, taking 4 of them gives you a substantial majority, specifically 80% of the whole. This calculation is useful in various contexts, such as grading systems, statistical analysis, and everyday evaluations.
