The answer is rational when you divide one whole number by another one.

-0.2 is another way of saying -1/5. It's rational.

All rational numbers can be expressed as one whole number over another whole number. 40.16 = 4016/100 = 1004/25 1004 is a whole number, 25 is a whole number, which means 1004/25, another way of writing 40.16, is one whole number over another whole number; → Yes, 40.16 is a rational number

If it can be expressed as a fraction then it is a rational number

It is rational, since it can be written as one whole number divided by another whole number. For example, it can be written as: 3122333444455555/1000000000000000. A somewhat laborious way to write a number, but it can be done.

The way in which the binary functions, addition and multiplication, are defined on the set of rational numbers ensures that the set is closed under these two operations.

A rational number is any number that can be made by dividing one integer by another.0.5 is a rational number as it can be made by dividing the number 1 by the number 22 is a rational number because it can be made by dividing 2 by 1-6.6 is a rational number because it can be made by dividing -66 by 10---------------------------------------------------------Note there are number that are called irrational numbers. Irrational numbers are all "real" numbers (numbers with a decimal point) that cannot be written as a simple fraction - the decimal goes on forever without repeating.For instance the number Pi is an irrational number.A rational number is a real number that can be expressed as a ratio of two integers. Another way to think about it is this: if you can write a number as a fraction then it's a rational number.

It is a rational number. One way this can be proved is that it can be represented as a fraction: 7/2.

As a terminating decimal 3.40764076407640764076 = 340764076407640764076/100000000000000000000 which is a rational number As an approximation to the recurring decimal 3.4076... = 34073/9999 which is a rational number. So either way, it is a rational number.

Either way, you'll end up with a rational number, but you won't get a sum if you multiply.

A rational number is a number that can be expressed as one integer divided by another. Decimals can only be expressed in such a way if they are repeating. For example 0.4646464646... is 46/99 and 0.333333.... is 1/3. Because pi is a non repeating decimal, it cannot be expressed in this way. Thus it is an irrational number.
