    Step-by-step explanation:

    500 test scores

    25 failing

    500 - 25 = 475 = passing scores

    passing:all scores

    475: 500

    Divide each side by 25

    475/25:500/25

    Simply subtract the fail rate from 100; the resulting number is the pass rate. So, if you know that 6 percent of students failed, you would subtract: 100 - 6 = 94 percent is the pass rate for the test.
