This is quite simple .ppt is Microsoft 2003 or earlier word file while .pptx is 2007 and up.
ppt = parts per thousand per cent = part per hundred so 10 ppt = 1 % and then 35 ppt = 3.5%
What is the difference between 392 and 247?
the difference is also doubled
There is no difference in value between "equal" fractions: the difference is zero.
A "difference" is either the result of a subtraction (the difference between 7 and 5 is 7 minus 5), or its absolute value (so that the difference between 7 and 5 is the same as the difference between 5 and 7).
.ppt is Microsoft 2003 or earlier word file while .pptx is 2007 and up.
.pptx
powerpoint extended or in short ppt extended
2 ppt=2000ppm
The earlier extension in power point was PPT. The newer extension is PPTX in power point.
In Microsoft Office 2007 and 2010, the extension is .pptx, whereas in earlier versions it was .ppt.
Up to version 2003 Word was .doc, Excel was .xls and Powerpoint was .ppt but that change when 2007 came along. An x was added to each one so Word is .docx, Excel is .xlsx and Powerpoint is .pptx now.Up to version 2003 Word was .doc, Excel was .xls and Powerpoint was .ppt but that change when 2007 came along.

I believe the default is .pptx (The old default used to be .ppt)
2 ppt=2000ppm
.ppt for versions up to 2003 and .pptx from version 2007 onwards.
.ppt is the file extension for power point files
