Converting Decimal Inches to Fractional Inches 

Thank you Tom! This is the second time, and my class just barely started, that I’ve used one of your videos to help me understand my plumbing homework for the course I’m taking at my local community college. You are a true blessing! Thank you!!!

What dictates whether you should round up or down? .5+ is rounded up and .4- is rounded down?

I love this way! Thanks Tom.

Thanks Tom! How about following up with a video adding and subtracting fractions which is what most of us would run across while laying out, say, a plumbing groundwork. If possible, can you use dimensions you would find in most commercial applications such as 3-5/8” plates and studs with 5/8” drywall. An example would be calculating from the inside of the framing of an outside wall, adding several rough wall dimensions of other rooms from the outside (original starting point) to the inside, then after getting to the rough wall behind a toilet, subtracting the 12-5/8” to obtain the measurement to the center of the closet flange from inside of the framing of the outside wall you began measuring from. Maybe, for a little more complication, you could add a 3/16” thick tile wainscoting behind the toilet. Throw in some 1/16”s, 1/8”s, 1/4”s, 1/2”s and 5/8”s. Thanks in advance!

So i got here cause i was needing that,im from italy and we use metric measure but im fascinated by inch,so my question is: giving a measure/result of a calcol converted to fraction will never be precise. is it true what am i saing? another question is: how do you round it? if you have for example 13.5 you go for 14 or 13? thank you.

This is not correct. 3 1/2 = 3.5 not 3.47
