Answer:
[tex]3\frac{1}{4}[/tex]
Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is
[tex]9\frac{3}{4} \\=\frac{36+3}{4}\\ =\frac{39}{4}[/tex]
Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-
[tex]\frac{\frac{39}{4}} {3} \\=\frac{39}{4} * \frac{1}{3} \\=\frac{13}{4}[/tex]
So, the distance between marker is
[tex]\frac{13}{4}[/tex]
Now, we have to convert this into mixed number.
Then, the distance is-
[tex]\frac{13}{4}\\ =3\frac{1}{4}[/tex]
