someone plz help me with this question
to pass a test in a water safety course,a student must get 80% of the questions correct.there are 90 questions on the test.how many questions must a student answer correctly to pass the test?
.80 * 90 = 72
To find out how many questions a student must answer correctly to pass the test, you need to calculate 80% of the total number of questions, which is 90 in this case.
To do this, multiply the total number of questions (90) by the percentage value (80%) converted to decimal form (0.8):
Number of questions to pass = Total number of questions * Percentage as a decimal
Number of questions to pass = 90 * 0.8
Number of questions to pass = 72
Therefore, a student must answer 72 questions correctly to pass the test.
