7/8 times 39/180 and simplify. I keep getting 273/1440 but it's telling me I'm wrong.

    it's correct :), you just need to SIMPLIFY it :)

    Sometimes. (-:. I guess I should divide 273 by 1440. Is that right?

    well, yes and no, you should to the extent you're still left with a fraction, so, \(\cfrac{2}{4} \ simplifies\ to\ \cfrac{1}{2}\)

    Ok, so that was easy. But I cant think of where to start. 273 is a large number as is 1440. Is there a trick?

    so \(\cfrac{1}{2}\times 2 = \cfrac{2}{4}\), same proportions, with just a multiplier, in this case "2"

    well, sorta, 273, 2+7+3 =12, 12 is divisible by 3, start from there, divide both by 3 :), see if that works

    Suppose it was 123/457?

    well, then I'd check what I can get from the numbers, usually you start small, 2, or 3, or 4 and so on, the smallest integer you can divide, NOT 1 of course, so 2 and so on, yo have 273, is not divisible by 2, so I checked with 3 :)

    let me see if I can make a quick table of both of those numbers, simplifying
