The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; "5" /"8" of them are seventh graders and "3" /"8" of them are eighth graders. If "4" /"5" of the seventh graders participated in track-and-field day and "7" /"8" of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.

Given that, the total number of students in seventh and eighth grade combined is 584.

The number of students in seventh grade= 5/8 of the total number of students.

As 4/5 of the total seventh-grade students participated in the track-and-field-event.

So, the number of seventh-grade students participated

The number of students in the eighth grade 3/8 of the total number of students.

As 7/8 of the total eighth-grade students participated in the track-and-field-event.

So, the number of seventh-grade students participated

The number of students must be a counting number, but here, as per the given information, the number of seventh-grade students participated coming out a fractional number, so the given information is incorrect.

Although, as per the given data, the mathematical value of the total number of students participated from both the grade combined

=292+191.625

=483.625 (mathematically)

Again, in real life, the fractional value of the total number of students is not possible.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

2
