I am trying to write a fraction in a matrix. I am doing it using the following code:

```
\[
\begin{bmatrix}
\frac{1}{6} & \frac{5}{6} & 0 & 0 \\
0 & 0 & 1 & 0 \\
0 & \frac{1}{6} & 0 & \frac{5}{6} \\
\frac{5}{6} & 0 & 0 & \frac{1}{6}
\end{bmatrix}
\]
```

What I get is as follows:

But what I am trying to achieve is:

Any help or suggestion will be appreciated.

Instead of writing

`\frac{a}{b}`

, use`a/b`

:In the second example above I've redefined the way

`\frac`

works to print it the way you want. Since the redefinition is done inside a display mathgroup, it's normal function will be reset after`\]`

.Of course, one could also redefine the way

`\frac`

works globally, but that would not make sense.
