If A Plank Of Wood Is Cut Into 12 Equal Peices What Fraction Of The Plank Is 7 Peices Search results?

7/12 is right - it's pretty simple: There are 12 pieces, you take 7 of them, that's 7/12 right there.

7 and 12 don't have a common multiple, so they can't be broken down any further my friend.

You could do that with 6/12 though, which would be 1/2..
