Yes.
Well, isn't that a happy little question! No, 2 over 15 is not irrational. In fact, it is a rational number because it can be expressed as a simple fraction. Just like painting a beautiful landscape, math can be quite lovely once you understand its different forms.

Oh, dude, yes, 15 over 7 is a rational number. Rational numbers are just numbers that can be expressed as a ratio of two integers, like a fancy math fraction. So, 15 over 7 totally fits the bill. It's like saying, "Hey, I'm a rational number, but I like to keep it interesting with a fraction twist."
If it ends there, it is rational. If it continues with the same digit (2 in this case) over and over, it is also rational.
Yes, 1 over 2 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are both integers. In this case, 1 over 2 is the fraction 1/2, which meets the criteria of being a rational number.
