# divide numerator and denominator by certain value

Hi,

is it somehow possible to divide the numerator and denominator of a fraction by the same value? For example, (a*b + c)/(b*d + a + c) gets (a + c/b)/(d + a/b + c/b) if I divide it by b.

For example:

```
sage: var('a b c d')
sage: q=(a*b+c)/(b*d+a+c)
sage: expand(numerator(q)/b)/expand(denominator(q)/b)
(a + c/b)/(d + a/b + c/b)
```

Display decimal as a fraction?

Division of polynomial matrices

eliminating fractions and roots from equations

Get a matrix to display answers as decimals/floats, not fraction?

dividing vector(a,b) by sqrt(x) gives (a/x*sqrt(x),b/x*sqrt(x))
