Yes, two thirds is a rational number. This is because it a is recurring decimal and can be expressed as a fraction. All fractions are rational numbers and all recurring decimals are rational numbers.
A rational number.
Yes because any number that can be expressed as a fraction is a rational number
Yes.
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.
No. It's the ratio of -17 and 3 ... a perfectly rational number.
2/3 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
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.
No, but three over eight is.
Eight and three thirds IS eight and three thirds. It is not an equivalence, it is an identity.
7/8 is a rational number because rational numbers are fractions, numbers that terminate, numbers that repeat.
