Default Finding Centers Fast

My father taught me this when I was a kid. To divide a fraction in half, all you have to do is multiply the denominator by two. For example: half of is . The denominator is multiplied by 2. I have found this to be very useful over the years especially when finding the center of a large room. This is very helpful when laying out hard tie ins in lay in panel type ceilings. Most all of the ceiling installers begin their lay outs from the center of the room.

If the room is 24- 6 3/8 wide, the math can be done quickly and the center of that dimension would be 12- 3 3/16. Almost too simple to figure and seems so obvious. I couldnt tell you how many people I have shared this with over the years that never looked at it that way. Hope this helps someone. This solution can also be worked in reverse, very useful.

Do you use a lot of metric in your shop?
While I agree metric is a better system, everything I do is standard.
Even all the blueprints I get are still standard.

Taking this step further. If you want to find half of a whole number and fraction where the whole number is an odd number. Figure out the highest number that whole number can be divided by 2. Then add the numerator and denominator together to get your new numerator and double the denominator to get your new denominator. Now to try and make this make any sense, I'll give an example. To find half of 13 5/8. 6 would be the highest number you could get if you divided 13 by 2. 5 + 8 = 13. 8 x 2 = 16. The answer would be 6 13/16. Hope this helps someone.
