Steps to convert from decimals to fractions:
For example the decimal number: 0.25
- First we must express the decimal number as a fraction, therefore, it is known that any number divided by one would result in the same number. In the form of a fraction it would be expressed as follows:
0.25 1 - We perform counting numbers to the right of the decimal point and multiplied by 10 to the amount of numbers. It is important to multiply the numerator and the denominator value unchanged fraction. The result obtained corresponds to the decimal number converted to a fraction.
0.25 x 10^{2} 1 x 10^{2} 0.25 x 100 1 x 100 25 100 - It is possible to rule out the third step, in this case consisting of verifying whether it is possible to simplify the fraction, in other words finding an equivalent fraction.
25 100 1 4 By dividing the numerator and denominator by 25 we obtain that the equivalent fraction is 1/4.

Trick to convert fractions to decimals
If in the fraction the denominator is 10,100, 1000, and so on we only have to traverse the point with respect to the number of zeros. Therefore, if the fraction can be simplified to a denominator of 1 with leading zeros, it would be easier to convert to decimals.
