Not necessarily. An irrational number is one that cannot be expressed as a simple fraction. But such numbers as one-third (rational) is also a repeating number (0.3333333r).
There are more irrational numbers in that interval than there are rational numbers in total!
No.
No. It is 1/pi where pi is the irrational number which is approximately equal to 3.14159
No. 27 to the third power is a regular whole number.
No. A rational number is any number whose magnitude is the ratio of whole numbers.The magnitude of (one third) is the ratio ( 1 / 3 ).
No, it is a rational number, as it can be expressed as a fraction, being one third.
No. One-third is a rational number. Any number that can be represented as a fraction using integers, like 1/3, 7/982, 67/5, etc. is rational.
Provided that the rational number is not 0, the product is irrational.
At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or irrational.
An irrational number is one which cannot be expressed as a ratio of two integers.
No. An irrational number has a whole number, followed by a decimal, which has no repeating pattern to it. For example, Pi: 3.14159265358979...... it goes on forever, with no pattern. unlike 5 and one-third: 5.33333333333333.... it goes on forever, but there is a pattern to it. or 4.12121212121212
An irrational number is a real number that is not rational. A rational number is one that can be expressed as a ratio of two integers. An irrational number cannot be expressed in this way.
Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!
An irrational number.
No. The sum of an irrational number and any other [real] number is irrational.
