20 Students

We're given that there are 25 students who participated in the survey about sports. Four fifths of them like football.

A simple method that works every time is taking your total value, #25#, and multiplying it by the value we want to find, #4/5#.

#= 25(4/5)#

#= 100/5#

#= 20#

We know know that #20# is equal to #4/5# of #25#. To check/reason, we can set up an equation.

x students = #4/5# students of #25# total students

x students = #4/5# students times (in math, #of# means to multiply) #25# total students

x students = #20# students

There! We proved that #4/5# of 25 is 20!
