Mario claims that if the dinominator of a fraction is a prime number, then its decimal form is a repeting decimal. Do you agree? Use an example to explain

I do not agree because Mario's claim is not general.

Step-by-step explanation:

Prime numbers: These are a set of numbers that are divisible by 1 and itself only. Examples are: 2, 3, 5, 7. 11 etc.

And a  denominator is the divisor in a given fraction.

Considering the following fractions whose denominators are prime numbers:

= 0.66666666...

= 0.142857142

= 0.45454545...

= 0.23076923

= 0.142857142

It could be observed that Mario's claim is not a general principle which is applicable to all fractions with a prime denominator. Thus, I do not agree with his claim.
