2. Convert to Decimal: Divide the numerator (45) by the denominator (60): 45 ÷ 60 = 0.75

3. Convert to Percentage: Multiply the decimal result by 100: 0.75 x 100 = 75

4. Add the Percentage Symbol: Add the "%" symbol to denote the percentage: 75%

Therefore, 45 out of 60 is equal to 75%.

A score of 75% is generally considered a good or satisfactory result in many contexts. However, the interpretation of this percentage depends heavily on the specific situation.
