Yes.
No, -5 is a negative, rational number.
Any number will be a rational number when multiplied.0 multiplied by any real number is rational and so it will produce a rational number when multiplied.If x is any non-zero number (rational or not), then since it is non-zero, 1/x is defined and x*(1/x) = 1 which is rational. So any non-zero number will produce a rational number when multiplied.Thus any number will produce a rational number when multiplied.
A terminating decimal is a rational number. A non-terminating, repeating decimal is a rational number. A non-terminating, non-repeating decimal is an irrational number.
All whole numbers are rational. Any rational number divided by another (non-zero) rational number is a rational number.
No. Irrational means "not rational". A number either is rational, or it is not rational - tercium non datur.
It is the smallest non-negative rational number. Negative numbers are rational and are smaller.
It is always FALSE.
A rational number is any number that is not irrational - that is, it can be designated with numbers (2, -5, 0, 1/3, 0.14, etc.) A non-negative rational number number is exactly what it sounds like. It's any rational number that is not negative.
It can be. 7 is a non-perfect square and, being an integer, it is rational.
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
Any number with terminating decimals (a finite number of decimal digits) is rational. (If it is non-terminating, but periodic, it is also rational.)
