Why the product of nonzero rational number and a rational number is an irrational
Actually the product of a nonzero rational number and another rational number will always be rational.
The product of a nonzero rational number and an IRrational number will always be irrational. (You have to include the "nonzero" caveat because zero times an irrational number is zero, which is rational)
Is an irrational number plus an irrational number rational
No.
The sum of an irrational number and any other [real] number is
irrational.
Which of the following statements is true if p is an integer and q is a nonzero integer
Then p/q is a rational number.
The sum of a rational number and an irrational number is
The sum of a rational and irrational number must be an
irrational number.
Which number produces a rational number when added to 0.25
Every rational number does.
What type of number cannot be written as a fraction pq where p and q are integers and q is not equal to zero
The number 0.4 can be written as 410 so it is a rational number
Which number produces a rational number when added to 15
Any rational number does.
How algebraic expression is a difference with two terms
An algebraic expression need not be a difference of two
terms.
Can 0.2 can be written as so it is a rational number
0.2 is a rational number. It can be written as 2/10
