Answer: No, 23/20 is a rational number.
Step-by-step explanation: Any rational number can be turned into a ratio, or a fraction. Since this is already in fraction form, we know that it is not an irrational number, but rather a rational one. Just to be sure, we can divide 23 by 20 and see if we get a rational or irrational number:
23 ÷ 20 = 1.15
We know that 1.15 is a rational number because it does not repeat.
Thus, we can conclude that 23/20 is a rational number.
