Well, honey, a rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. So, if you can write 15 over 4 as a fraction (15/4), then yes, it's a rational number. Don't stress, math can be a real pain in the behind sometimes, but this one's a no-brainer.
Yes.
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."
