Start by breaking the equation down to a simpler form. To do this you would need to divide 28 by 7.
28 / 7 = x
x = 4
Now we can create a new equation.
4x = t
T would represent the total number of students in the band. X would be the any number from 1 to 10. This is because 10 is the highest faction to make the fraction a whole. Since we a looking for the total we would put ten in place for x.
