| yesterday | comment | added | pancini | @SeanRoberson $\ast$ is still in common usage for multiplication. They surely meant to have $b$ and $d$ swapped though, as 2'5 9'2 said. | |
| yesterday | comment | added | 2'5 9'2 | As written, this is incorrect. But you could compare $ad$ with $bc$. Is that what you mean? | |

Welcome to Math.SE! Did you mean to write "I can compare fractions by doing $a \cdot d, b \cdot c$" in the body? I kept the meaning while removing the $*$ symbol (you can use \cdot instead or just juxtapose).
