Solve for x: Divide both sides by 15: x = 1400/15 = 93.333...
Express as a percentage: x = 93.33...% Again, rounding to two decimal places gives us 93.33%.

Method 3: Using a Calculator

Most calculators have a percentage function. Simply enter 14 ÷ 15 and then multiply by 100 to obtain the percentage.

Understanding the Result: 93.33%
