Is negative two thirds an rational number?
Yes.
Is two thirds a rational or an irrational number?
2/3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Is 21.6 repeating rational?
It would be 21 and two thirds, so it can be expressed as a fraction and is therefore rational.
Can you add two rational numbers and get a rational number?
Every time. The sum of two rational numbers MUST be a rational number.
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.
Is negative two thirds an rational number?
Yes.
Is two thirds rational?
Yes, two-thirds is a rational number because it can be expressed as the fraction ( \frac{2}{3} ), where both the numerator (2) and the denominator (3) are integers, and the denominator is not zero. Rational numbers are defined as numbers that can be written as the quotient of two integers, and two-thirds meets this criterion.
Is -5 and two thirds an irrational number?
No. It's the ratio of -17 and 3 ... a perfectly rational number.
Is six and two thirds rational or irrational?
It's rational
Is two thirds a rational or an irrational number?
2/3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
What is 3 and one- thirds?
A rational number.
Is 2 thirds a rational number?
Yes because any number that can be expressed as a fraction is a rational number
Is the square root of 2 and 2 thirds rational?
The square root of 2 is an irrational number, as it cannot be expressed as a fraction of two integers. However, 2 thirds (or ( \frac{2}{3} )) is a rational number because it can be expressed as a fraction where both the numerator and denominator are integers. Therefore, while 2 thirds is rational, the square root of 2 is not.
Is eight thirds a rational number?
Yes.
Is thirty thirds rational or irrational?
A rational number is one which can be expressed as one integer over another (possibly the same) integer which is not zero. thirty thirds = 30/3 which is one integer over another integer → it is rational.
Is 21.6 repeating rational?
It would be 21 and two thirds, so it can be expressed as a fraction and is therefore rational.
Is thirty thirds rational?
30 / 3 = 10 10 is an integer, so of course it is rational! Any number that can be exactly expressed as a ratio is by definition rational.
