A student received a score of 38/50 on a math test and wants to convert the points into percentages.

To convert a test score to a percentage, divide the number of correct answers by the total number of questions, then multiply by 100. Here, 38 ÷ 50 = 0.76, and 0.76 × 100 = 76%. Choice D, “number of correct answers by the total number of questions,” gives the correct calculation.
