no. you can think of an irrational number as any number you don't know the last digit of. 1/2 is = to 0.5. because you know 5 is the last digit, it is rational. pi is irrational, because it does not have a last digit, it goes on forever. 10/3 or 3.33333 repeating is rational because you know 3 will be the last digit even if it is infinite. 6.7878787878 repeating would be irrational because it is not known if the 7 or the 8 is the last digit
No, it cannot. The product of a rational and irrational is always irrational. And half a number is equivalent to multiplication by 0.5
Provided that the rational number is not 0, the product is irrational.
The sum of a rational and irrational number must be an irrational number.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
no

There are more irrational numbers in that interval than there are rational numbers in total!
As a number which can be expressed as a fraction, 1/2 is a rational number.
No.
No because -1/2 is a rational number expressed as a fraction
1.5 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
The number -1/2 is a rational number, a negative integer divided by a positive integer.
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.
No. It can be written as a fraction, so it is rational.
