Aus Online Mathematik Brückenkurs 1
If we divide up the denominators into their smallest possible integer factors,
the expression can be written as
and then we see that the denominators have \displaystyle 3\cdot 5 as a common factor. Therefore, if we multiply the top and bottom of the first fraction by 5 and the second by 3, the result is the lowest possible denominator
The lowest common denominator is 225.
