    How to calculate 18 out of 23 as a percentage

    To calculate 18 out of 23 as a percentage, you divide 18 by 23 and then multiply by 100:

    (18 ÷ 23) × 100 = 78.26%

    This calculation gives you your percentage score, which can then be converted to a letter grade based on your school or institution's grading scale.

    Step-by-step explanation:

    1. Divide the points earned (18) by the total points possible (23):
      18 ÷ 23 = 0.7826
    2. Multiply the result by 100 to get the percentage:
      0.7826 × 100 = 78.26%
    3. Convert the percentage to a letter grade using the standard scale:
      78.26% = C+
