Q. Lincoln valley elementary held its annul skating party and 3 fourths of the 400 students came. Of the students who came,1 fifths brought skates from home. How many students rented skates?
A. Do I mulpite 400 by 3 fourths than get the answer than mulpite 1 fifths by the answer.

  • Math -

    Yes -- 400 * (3/4) =

    Multiply that product by 4/5 to find how many rented skates.

  • Math -

    yes, but that would give you how many brought skates, which is not the question.

    First, how many came ?
    (3/4) of 400 = 300

    of those 1/5 brought skates
    number who brought skates = (1/5)(300) = 60

    Assuming the rest rented skates,
    so 300-60 or 240 rented skates

    or

    if 1/5 brought skates, then 4/5 rented skates
    (4/5)of 300 = 240

  • Math -

    So 240?

  • Math -

    Yes.
