Yes, -0.15 is a rational number. A rational number is any number that can be expressed as a ratio of two integers, where the denominator is not zero. In this case, -0.15 can be expressed as -15/100, which is a ratio of two integers (-15 and 100). Therefore, -0.15 is a rational number.

DevinYes, because you can express it as a ratio of two integers, for example, -15 / 100. This can be simplified, but that's not necessary to prove it is rational.

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.
Is 5 over 9 rational?
Yes. Any rational number divided by another rational number is also rational.
