The number 1.21 is rational because it can be expressed as a fraction p/q where p and q are both integers.

1.21 = 121/100. Thus, it is rational.

In general, any number which can be expressed as a fraction, or a decimal which terminates (like 1.21) or repeats (like 1/3 = 0.3333...) is rational. All other real numbers are irrational.
