The best way to do show you my methods of conversion is through showing them to you. Let's use .54 as an example. The first thing is to move the decimal over 2 places to the right and put it over 100. This gives you 54/100. The next step is to divide both the numerator and the denominator by the same number. I will divide by 2. This leaves us with 27/50. This can not be simplified. We are now done. I will show you another example.
This time I will use 80/100. I will divide the numerator and denominator by a common number. Since both the numerator and the denominator are divisible by 10, I will divide 80/100 by 10. This leaves us with 40/50. Since both the numerator and the denominator are divisible by 10, I will divide them by ten leaving use with 4/5. Instead of dividing twice, I could have divided 80/100 by 20 which would have left use with 4/5. In my opinion, this is the best method to converting decimals to fractions, and this is the only method I know. If there is a different method please post this method in the comments, and also if you like this method more than the method you were taught; please let me know in the comments.
