Question 342267
On Bill's football squad, 1/3 of the players walk to practice and 25% are driven by their parent. The remaining 15 players take the bus. How many members are on the football squad?


Since {{{1/3}}} walk to practice and 25% or {{{1/4}}} are driven, then the remaining fraction of the squad is: {{{5/12}}} ({{{1 - (1/3 + 1/4)}}})


We can now set up the following proportion to solve, since the remaining fraction, {{{5/12}}} represents the 15 remaining members, and also using M to represent the total amount of members:


{{{(5/12)/1 = 15/M}}}


Cross-multiplying, we get: {{{5M/12 = 15}}}


5M = 12*15


M, or amount of members = {{{(12*15)/5}}} or {{{highlight_green(36)}}}


I will leave the check to you to verify the accuracy of this answer.
