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"

Answer 5 months

Of course, I can help you with that! To find the fraction that represents the part of the school population in each grade, we need to divide the number of students in each grade by the total number of students in the school.

First, let's find the total number of students in the school:
Total number of students = Number of 6th graders + Number of 7th graders + Number of 8th graders

Total number of students = 58 + 76 + 38
Total number of students = 172

Now, we can calculate the fractions:

Fraction of 6th graders = Number of 6th graders / Total number of students
Fraction of 6th graders = 58 / 172
Fraction of 6th graders = 0.3372 (approximately)

Fraction of 7th graders = Number of 7th graders / Total number of students
Fraction of 7th graders = 76 / 172
Fraction of 7th graders = 0.4419 (approximately)

Fraction of 8th graders = Number of 8th graders / Total number of students
Fraction of 8th graders = 38 / 172
Fraction of 8th graders = 0.2209 (approximately)

Therefore, the fractions representing the part of the school population in each grade are as follows:

6th graders: approximately 0.3372
7th graders: approximately 0.4419
8th graders: approximately 0.2209
