HELP PLSS THIS IS A TEST (NO LINKS)

Step-by-step explanation:

We need to count the total distance that all the students ran. We first need to identify that the X represents one student. So, we can see that 2 students ran 1/4 of a kilometer, 1 student ran 3/4 of a kilometer, etc.

Let's start off with the students we see that have ran of a kilometer.

There are two students who have done this, so we have:

= 2()

=

Next, we have the students that ran of a kilometer.

There is only one student that did this, so we have:

= 1 ()

=

Now, we have the students that ran 1 of a kilometer, or of a kilometer.

There are two students who have done this, so we have:

= 2()

=

=

Lastly, we have the students that ran 1 of a kilometer, or .

There is only one student who did this, so we have:

= 1 ( )

=

Since we have all the distances now, we have to add them up!

= + +   +

We need to find a common denominator, which is 4.

= + + +

=

This can be simplified to:

=

Hope this helps! :)
