At wallys school 30% of the student are in 8th grade if there are 470 students total find the number of 8th grade students

30%*470=141 (So the number of students in 8 grade is 141)

To find 30% of 470 students we want to do 470*0.30. The 0.30 is the decimal format of 30% because you move the decimal twice to the left. And the asterisk (*) represents multiplication.

When you do 470*0.30 you get 141 students 

Hope this helps.

Basic algebra equation. first set up your equation: divide out 9.and now you are left with 2x + 4 = 8.
