Changing decimals to fractions?

We all learnt about changing numbers into different forms.

Decimals <-> Percentages <-> Fractions

We can change all decimals to percentages and vice versa (because it is just merely a shift of the decimal point)

We can also change all fractions to decimals (we divide the numerator by the denominator, and we can change any fractions to decimals)

Problem now:

Is it true that we can change any decimal to a fraction?

Or can you find any decimals, so special that we are unable to change into a fraction?

square root of two

pi

e

any transedental numbers

professor, i dont understand

pi cannot be ended and contains no pattern-no accurate fraction

e is (1/infinity+1)^infinity---since infinity is not a number ,,,e values can only be estimated

if infinity can not be calculated

how can we estimate e????

we all agree that infinity is a big number,

so we use big numbers to replace infinity

in fact, all irrational numbers cant be turned into fractions
