Answer:
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! :)
