PDF is a very popular document format. It supports almost every platform and has excellent print effect. These make it widely used in various fields. But one annoying thing of this format is that most PDF files are not editable as they are protected. Fortunately we find a solution for this problem - converting PDF to Word and edit the docx (or doc) file in Microsoft Word. This article shows you four methods of converting PDF to Word. You may need to pay some money in some methods.
Method 1. Convert PDF to Word with Microsoft Word
Just open the PDF with Adobe Reader, save it as text file (.txt), copy the text and paste it in a new Microsoft Word, then save as Word. Sounds very easy, isn't it? But this method can only save text content. All the images in the original PDF file will lose. If the PDF content contains nothing but text, you can try this. Otherwise you'd better try other methods below.
Method 2. Convert PDF to Word with Adobe ExportPDF
Like mentioned above, most people use Adobe Reader to read PDF files. So it's natural to think of converting PDF to word with Adobe Reader. But we can't find the 'save as word' option in it, so you need to purchase the 'Adobe ExportPDF' service. Click 'Tools' – 'Export PDF' – 'Convert' then your PDF file will be converted to Word (docx or doc). This conversion service could generate very high-quality file and it's very suitable for business. Click here to get more information of Adobe ExportPDF.
You can also purchase Adobe Acrobat. It's a comprehensive PDF management. You can edit and convert PDF files directly. But it's a bit expensive.
Method 3. Convert PDF to Word online
Online conversion is very simple and easy. Just upload your files and click, then all things done. There are so many websites providing conversion service but not all of them are good. You can only convert limited pages or the converted Word file has low quality. Here I recommend you this website: http://convertonlinefree.com/PDFToWORDEN.aspx. It's totally free and has high quality conversion.
Just select any PDF file from your PC and click the 'convert' button. The conversion will take several minutes. It depends on the file size and Internet connection speed. The download window will pop up automatically after conversion finished. If you use Microsoft Word 2003 or lower version, please choose 'PDF to DOC' option.

To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number), using either calculator or pencil and paper. For example, here’s how to convert the fraction
to a decimal:
So,
To convert a decimal to a fraction, begin by placing that decimal over the number 1. Then keep multiplying both the numerator (top number) and denominator (bottom number) by 10 until both are whole numbers. For example, here’s how to convert the decimal 0.13 to a fraction:

In both of these cases, the decimal forms of these numbers are terminating decimals — that is, the decimal can be written exactly in a finite number of decimal places.
In other cases, however, a decimal is repeating — that is, it cannot be written exactly without the numbers repeating forever.
Converting fractions to repeating decimals
Every fraction can be written as a decimal, either terminating or repeating. To write a fraction as a decimal, divide the numerator by the denominator. For example, here’s how you convert the fraction
to a decimal:
You can see that this decimal will never end, but instead will repeat forever in a pattern of 1s and 8s. Therefore,
The bar over the numbers 18 means that these numbers are repeated infinitely: 0.1818181818. . . .
As another example, convert the fraction
to a decimal by dividing:

As in the previous example, the pattern of numbers in the answer repeats itself and will do so indefinitely. So,
Converting repeating decimals to fractions
Every repeating decimal can be written as a fraction. A quick trick for converting a repeating decimal is to place the repeating numbers in the numerator of a fraction over the same number of 9s, and then reduce if necessary. For example, here’s how you convert the repeating decimals
and
to fractions:
To gain insight into why this trick works, here is a step-by-step way to convert a repeating decimal to a fraction using algebra. Suppose you want to convert the decimal
to a fraction. Begin by letting x equal
This decimal has two repeating decimal places, so multiply both sides of this equation by 100 — that is, the number that brings the whole repeating pattern to the left side of the decimal point:
Note that this decimal still repeats forever. Now, subtract the original equation from this one:
This step may seem strange, because on the right side of the equation you’re subtracting an infinite decimal from an infinite decimal. But this process removes the repeating decimal from the equation. Now, to solve for x, just divide by 99:
As you can see, the result shows that
