"Rational number" means you can write them as a fraction, with integers on top and bottom. You can get an exact result by adding them as fractions. You can get an approximate result - usually with a small error, but you can make that error as small as you want - by adding them as decimals.

Yes. Since 0.555 and 0.5 are both rational numbers, their product will be rational.
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.

Since 0.25 is a rational number, you need to add another rational number. Any rational number will do. Try .75. Then you will get 1.
When added to a rational number, any irrational number will produce an irrational number.also, when added to an irrational number, any rational number will produce an irrational number.
Any integer or any fraction will do such as 1+0.25 = 1.25 or 1/2+0.25 = 0.5
