No. It is a terminating decimal and therefore can be expressed as a ratio ie it is rational. 3.8 = 38/10 (which can be simplified)
No, the number 38.4 is a rational number. It can be expressed as a fraction, which is a characteristic of rational numbers. 38 4/10, or 384/10.
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.
Any irrational number added substracted multiplied or divided into a rational number produces an irrational answer.
it is a rational number but 4.121314..... is an irrational no
It is an irrational number.
No, it is rational.
An irrational number is one that can NOT be expressed as a fraction, with integer numerator and denominator. 3.8 CAN be expressed as such, namely, 38/10, so it is RATIONAL.
Yes because it can't be expressed as a fraction
No; it is a rational number. An irrational number has a non-terminating, non-repeating decimal. 12.666666666 either terminates (= 12666666666/1000000000) or if you mean the 6 recurs (ie goes on forever: 12.666... = 38/3).
No, the number 38.4 is a rational number. It can be expressed as a fraction, which is a characteristic of rational numbers. 38 4/10, or 384/10.
An irrational number.
The sum of a rational and irrational number must be an irrational number.
No. The sum of an irrational number and any other [real] number is irrational.
Yes.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
