Math 7 . grade 7.

solve equations with rational coefficients:

24 students brought their permission slips to attend the class field trip to the local are museum. if this represented 8/10 of the class, how many students are in the class?

let s = the amount of students total in the class.

identify the equation you would use to solve this problem.

options:

a) s + 8/10 = 24

b) 8/10s = 24

c) s/24 = 8/10

d)8/10 x 24 = s

type just letter choice:

now, solve the above equation selected:

s = ? students
