Any already rational number
Yes.
It is the smallest non-negative rational number. Negative numbers are rational and are smaller.
Only if the rational number is 0.
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.
Every rational number does.
Every rational number does.
Any irrational number multiplied by 0.5 will remain irrational. Any rational number multiplied by 0.5 will remain rational.
Yes, unless the rational number is 0.
Any and every rational number.
