Since all counting numbers are rational numbers, arithmetic would never have started. There would have been no science nor technology.

Is a fraction never a rational number?
Fractions where both the numerator and divisor are rational numbers are always rational numbers.
Are irrational numbers never rational numbers?
Yes, irrational numbers are never rational numbers because irrational numbers can't be expressed, by definition, as a fraction of two integers.
Is the quotient of two nonzero numbers never a rational number?
The quotient of two nonzero integers is the definition of a rational number. There are nonzero numbers other than integers (imaginary, rational non-integers) that the quotient of would not be a rational number. If the two nonzero numbers are rational themselves, then the quotient will be rational. (For example, 4 divided by 2 is 2: all of those numbers are rational).
Is the product of two rational numbers never equal to 1?
False.
Is the product of two rational numbers is never equal to 1?
yes
Will repeating decimals always or never be rational numbers?
They will always be rational numbers.
Is a fraction never a rational number?
Fractions where both the numerator and divisor are rational numbers are always rational numbers.
Are irrational numbers never rational numbers?
Yes, irrational numbers are never rational numbers because irrational numbers can't be expressed, by definition, as a fraction of two integers.
Can rational numbers be irrational numbers?
No, they are two separate groups of numbers. A number is either rational or irrational, never both.
What will happen if pizza never existed?
Nothing would happen. If pizza never existed, we would simply be eating something else.
Are integers rational?
Integers are whole numbers. Rational numbers can be fractions / decimals. But it is NEVER a whole number E.G. of rational numbers : 3/4 or 1.5
The sum of two rational numbers is a rational number?
Always true. (Never forget that whole numbers are rational numbers too - use a denominator of 1 yielding an improper fraction of the form of all rational numbers namely a/b.)
What if the world never existed?
Who knows what would happen?
What is an irrational number that is also rational?
Numbers are either irrational (like the square root of 2 or pi) or rational (can be stated as a fraction using whole numbers). Irrational numbers are never rational.
Are integers rational numbers?
Integers are whole numbers. Rational numbers can be fractions / decimals. But it is NEVER a whole number E.G. of rational numbers : 3/4 or 1.5
When adding two rational numbers with different signs the sum will be zero Is this aways sometimes or never true?
sometimes true (when the rational numbers are the same)
Is Sum of two rational numbers Can never be an integer?
Wrong because 3/4 and a 1/4 are rational numbers that add up to 1
