    What does this mean?

    A couple of my buddies are confuse to what the following means

    $\displaystyle EF$ $\displaystyle :$ $\displaystyle FO$ $\displaystyle ::$ $\displaystyle DB$ $\displaystyle : $ $\displaystyle BO$

    We are looking at length of line segments. I was telling them that the colons mean that they are proportional.
    What do the colons mean?

    What do the colons mean?
    EF is to FO as DB is to BO

    $\displaystyle \frac{EF}{FO} = \frac{DB}{BO}$
