Question

On a recent test, rudi correctly answered 30 out of 40 questions. What percent of her questions did rudi answer correctly?

1 Answer

  • Step-by-step explanation:

    First we put this into a fraction

    30

    40

    The bottom number must reach 100

    This means we must divide 100 by 40

    This gives us 2.5

    Therefore we multiply 30 by 2.5 to give us

    75

    So therefore she got 75% of all questions right
