Since a rational number is a number that can be expressed precisely as the ratio of two integers, can the infinite circular decimal in a rational number also accurately represent the ratio of two integers?

In that case of rational infinite circular decimal,
Fraction line up and down can be integer ah, fraction line and proportion number equivalent
Of course it can be expressed as a ratio of two integers
E.g. infinite repeating decimal 3.333... =10/3(Fraction)=10:3(form of two integer ratios)
A rational number can be regarded as a fraction with positive and negative points
