Oh, dude, you're hitting me with the math questions. Okay, so a rational number is any number that can be expressed as a fraction, right? And 6.28 can totally be written as 628/100, which is a fraction, so yeah, it's a rational number. But like, who even uses fractions these days anyway?

Is 628 on a ring mean its real.?
In mathematics, the concept of a "ring" refers to a specific algebraic structure. The number 628 being on a ring does not inherently imply that it is a real number. In the context of rings, elements can be integers, rational numbers, complex numbers, or other mathematical objects, but the term "real" typically refers to a subset of numbers on the real number line. Therefore, without additional context or clarification, it is not accurate to conclude that 628 being on a ring means it is a real number.
Is the product of a rational number and a rational number a rational number?
yes
Is a rational number multiplied a rational number rational?
Yes.
Is the number 17.5 a rational number?
yes
Which number can be multiplied to a rational number to explain that the product of two rational numbers is rational?
It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
