I have a math question that I do not really understand how to answer is there someone who can walk me through it?
In Pinecrest middle school there are 58 6th graders 76 7th graders, and 38 8th graders. The counsel is made up of 35 students who are chosen to represent all three grades fairly. Write fractions to represent the part of the school population that is in each grade?

there are 58+76+38=172 students
So, if a bunch is chosen to represent the classes in proportion to their size, then
58/172 of them will be 6th graders, and so on for the other grades.
So, since 35 were chosen,
58/172 * 35 = 11.8 will be 6th graders. So, better make that 12.
Similarly for the other grades. If rounding causes the total to be different from 35, then make suitable adjustments.
By the way, that's "council" not "counsel"
