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.
Yes -- 400 * (3/4) =
Multiply that product by 4/5 to find how many rented skates.
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
if 1/5 brought skates, then 4/5 rented skates
(4/5)of 300 = 240
