1. Form a Fraction: Express the score as a fraction. In this case, it's 16/20.

2. Convert the Fraction to a Decimal: Divide the numerator (16) by the denominator (20). 16 ÷ 20 = 0.8

3. Convert the Decimal to a Percentage: Multiply the decimal by 100%. 0.8 x 100% = 80%

Therefore, a score of 16 out of 20 is equivalent to 80%.

Alternative Calculation Methods

While the above method is straightforward, there are other ways to approach this calculation:

This simplifies the fraction to 4/5. Then, convert 4/5 to a decimal (4 ÷ 5 = 0.8) and then to a percentage (0.8 x 100% = 80%). This method can be helpful with larger numbers.

• Using a Calculator: Most calculators have a percentage function that can directly calculate percentages. Simply enter 16 ÷ 20 and then multiply by 100 to get the result.
