There are infinitely many fractions which must be represented by non-terminating decimals, not just one.
155 is an integer not a fraction.
The relationship between fractions and decimals can be seen as follow. Fractions can be represented as ratio of two numbers and on dividing can give a decimal value. And decimal value can be converted into a fraction too.
Restate the question: If you can write a fraction as a decimal, can you write a decimal as a fraction?Yes.
how to turn fractions into decimals
If you convert repeating decimals into a fraction, you see that the repeating decimals are rational.
The answer will depend on what you wish to convert the decimals into!
You can multiply it by the denominator of the fraction you want to turn it in to. For example, .125 * 8 = 1, therefore, 1/8 = .125. Keep in mind that only some decimals can be made into simplified fractions. For example, .453 can be represented in simplest form as 453/1000.
you can change the fraction into a decimal or vice-versa
Of course all the decimals have fractions except those with non-recurring and non-terminating decimals.
