Yes, 9.2 is a rational number because it can be expressed as the fraction 92/10, which simplifies to 46/5. Rational numbers are defined as numbers that can be written as a ratio of two integers, and since 9.2 meets this criterion, it is considered rational.
Yes
9.2 = 92/10 and so is rational.
No
YES * * * * * No, it is not. 9.2 = 92/10 and so it is rational.
-0.92 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its rational equivalent is -92/100 which can be simplified.

Rational
Sure. Let's take an example with numbers instead of variables. 8/9 is a rational number - the ratio of two integers. If you square it, you get (8/9)2 = 82/92 = 64/81; that is, if you square each integer, you get an integer again. Therefore, the resulting number is rational again - a number that can be expressed as the ratio of two integers. Replace with any other integers; you will still have a ratio of integers if you square it.
