Calculating the Percentage: 18 out of 26

To find what percentage 18 is of 26, we follow these steps:

Set up the Fraction: First, write the numbers as a fraction. The part (18) goes on top, and the whole (26) goes on the bottom: 18/26
Convert to Decimal: Divide the numerator (18) by the denominator (26): 18 ÷ 26 ≈ 0.6923
