Yes, unless the decimal (not desimal!) terminates.
There are 99999 fractions with a 1-digit numerator and 5-digit denominator - 6 digits in all: though not all the fractions are different. Similarly there are 8,999,910 fractions with a 2-digit numerator and 4-digit denominator. And so on. In total, there are 3,600,009 fractions using 6 numbers.
Answer: Yes. Every number that you can completely write with digits, and a fraction bar or a decimal point if you need them, is rational. Answer: Yes, if the numerator and the denominator are whole numbers.
If the denominator of the fraction has any prime factor other than 2 or 5, then it has a decimal representation with a repeating sequence of digits. If the denominator is a product of any number of 2s or 5s then it can be represented as a terminating decimal.
, divide the numerator by the denominator. To change terminal decimals into fractions, count the number of decimal places, put the decimal's digits over 1 followed by the proper number of zeroes.
You can compare two fractions by converting them to a common denominator - but if you need to compare several fractions, it would be easier to write each fraction as a decimal, with several digits after the decimal point, then compare the decimals.

change the denominator into 10 or 100 etc. according to the number of decimal digits eg. 1.23 = 123/100
0.601 = 601/1000The number of zeros after the 1 in the denominator = number of digits after the decimal point in the original decimal number.

-- Take one whole set of the digits that repeat in the decimal. Write them as the numerator of the fraction. -- For the denominator of the fraction, write a group of 9s ... the same number of them as there are digits in the numerator. -- Simplify the fraction, if possible and if you feel like it.

Example, add 0.3 + 0.5, which equals 0.8...convert these to fractions and you see they both have the same denominator: 10 so, it would be the same as 3/10 + 5/10...since they have the same denominator adding the fractions topgether would be (3+5)/10 or 8/10. This is the same result as lining up the decimals and adding the digits: 0.3 + 0.5 = 0.(3+5) = 0.8
Count the number of digits after the decimal point. The denominator is 1 followed by the same number of 0s.So, for example, 12.0356 has 4 digits after the decimal place. Therefore the denominator is 10000, and the rational form is 120356/10000
Put the digits after the decimal point as the numerator over 1 followed by the same number of zeros as digits as the denominator and simplify. In this case, the numerator is 1504 and as there are 4 digits after the decimal point the denominator is 10000.
Do a division with denominator 11.
