0.9 would be a rational number because it can be written as a fraction. It would be 9/10, therefore, it is a rational number.

Yes 0.9 is a rational number because it can be expressed as a fraction and in this case 9/10 would be the case

A rational number is a number that can be written as a fraction. .9 = 90/100 = 9/10, so therefore it is rational.

it is rational becuase it doesn repeat, therefore u can turn it into a ratio [thats how i remember it]. once u have a fraction u can turn it into a ratio because a ratio is the numerator:denominator. .9=9/10, so the ratio is 9:10. since a ratio is equal to a corresponding fraction, percent, and decimal, if u can turn a number into any of them, it is a rational number.

Any terminating (non-infinite) fraction is rational. Also, some non-terminating fractions (repeating fractions, specifically) are rational. This falls into the first category, or RATIONAL.
