No. A rational number is one that may be represented as a simple multiple, or a division. Such as one times seven, or three times seven; OR one divided by seven, or three divided by seven. Or similar.
A rational number, if a fraction, when multiplied by the divisor of the fraction, will give a simple whole number. e.g. 7/5, when multiplied by 5 becomes the whole number 7.
An irrational number is one that cannot be formed by a simple ratio, or a simple division. e and pi are a couple of common Irrational Numbers. [irrational demonstrates where the name comes from.]
No number can be found which will convert them, by multiplication, into a whole number.

∙ 9y agoThe answer depends on what you mean by "opposite". The additive inverse of any rational number must be rational. The multiplicative inverse of a rational number is rational only if the number is non-zero. If it is zero, its "opposite" is not defined.

How do you identify opposite and absolute value of a rational number?
how do you identify opposite and absolute value of a rational number
Must a rational number be rational?
Yes, if it wasn't it wouldn't be a rational number.
What number can you divide a rational number to get a number that is twice the opposite of the rational number?
You would need to divide by -1/2.
May the sum of a rational and an irrational number only be a rational number?
No. In fact the sum of a rational and an irrational MUST be irrational.
The mode of a list of rational numbers must be a rational number?
false
How do you identity the opposite and the absolute value of a rational number?
The additive opposite of the rational number q is -q. One of q and -q must be non-negative and that is its absolute value.

Must a rational number be rational?
Yes, if it wasn't it wouldn't be a rational number.
What number can you divide a rational number to get a number that is twice the opposite of the rational number?
You would need to divide by -1/2.
What is the opposite of a nonzero rational number?
The answer depends on whether you mean an additive opposite or a multiplicative opposite.
Must the difference between two rational be a rational number?
Yes, it must.
When are the absolute value and the opposite of rational number equal?
When the number is 0.
What is the additive inverse of a rational number?
It is the number with the same magnitude (absolute value) and the opposite sign.
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.
Can you add two rational numbers and get a rational number?
Every time. The sum of two rational numbers MUST be a rational number.
How do you identify opposites and absolute value of rational numbers?

What is a rational number whose opposite and absolute value are the same?
They are all non-positive rational numbers.
