Percent meet almost continually. Discount campaigns, calculation of tax or other rates, various share and fractional ratios. But transfer of percent to number is not so difficult.
Instruction
1. The percent is by definition a hundredth part of number. Therefore 100% are actually unit, that is initial number. Percent which size less than 100, designate a share from initial number, more than 100 - excess of initial number. For usability the percent write down usually in the form of numbers from 1 to 100. Just most often we face sizes from this range. As well as any number, at percent has tenth, 100-th and other shares too. Most often they meet during the work with finance and other economic operations and also at representation of several sizes, a component of whole.
2. Now we will be engaged directly in transfer of percent to number. It is not difficult at all. As it was already told above, 1% is the 100-th share from whole. Whole there is unit, 1% = 0.01 means. So that to transfer percent to number, it is necessary to divide this number of percent into 100, or, in other words, to shift a comma in this number on two signs to the left, that is on two orders.
3. Functions for work with percent also are practically in any, even the simplest calculator, but as you can see, this operation is very simple and does not demand any special efforts or knowledge in the field of mathematics. Actually, it is necessary to remember the only formula. The fraction received as a result of this action will be decimal, and it, in turn, it is possible to transfer to ordinary, having presented as the significant figures of decimal fraction divided on 10 in the corresponding degree. Decimal fractions in general very well are perceived and register in hearing, most likely became an occasion of use 10 in the second degree, that is 100 as in the main unit of percent. Further it can be simplified, having divided numerator and a denominator into their general multiplier. For example: 50% = 0.5 = 5/10 = 1/2. Also the return action will be also right (try to transform this example from right to left).
