Hi,

is it somehow possible to divide the numerator and denominator of a fraction by the same value? For example, (ab + c)/(bd + 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)

Hey @achrzesz, great answers lately - just a reminder that if you indent a code block (or highlight it and click the "010101" button) then it will "look right".
