The percentages are found almost everywhere. Discount shares, calculating tax or other rates, various equity and fractional ratio.
But translation percent in the number of not too complicated.
Percentage - is by definition a hundredth part of the number. Therefore, 100% - it is actually a unit that is itself the original number. Interest, the value of which is less than 100, represent a fraction of the original number, more than 100 - exceeding the original number.
For ease of use percentages recordedusually in the form of numbers from 1 to 100. Just more often we are confronted with the values from this particular range. As with any number, at interest, too, are tenths, hundredths and other shares.
Most often they are found when dealing with finances and other economic transactions, as well as the presentation of several variables that make up part of the whole.
Now for direct transferpercent of a number. It is not difficult. As mentioned above, a 1% fraction is a cell from a whole. Integer is a unit, then 1% = 0.01. Thus, to translate the percentage in number, this number must be divided by 100 percent, or, in other words, in this slide comma including two left mark, that is two orders of magnitude.
Functions also have interestalmost any, even the most simple calculator, but as you can see, this operation is very simple and does not require any special effort or knowledge in the field of mathematics. In fact, you need to remember a single formula. The resulting action is a decimal fraction, and it, in turn, can be converted into common, presenting a significant digits decimal, divided by 10 in a corresponding degree. Decimal fractions are generally very well received and recorded at the hearing, most likely it was the reason the use of 10 in the second degree, that is 100, as the basic unit of interest. Further, it can be simplified by dividing the numerator and denominator by their common factor. For example: 50% = 0.5 = 5/10 = 1.2.
Also true is the opposite effect (try to convert the example from right to left).
