Negative sign affects whether or not a number is a rational number?
Only if the negative sign is associated with an even root. In that case, the number is neither rational nor irrational, but is imaginary.
Which statement is true Converting an integer to a fraction shows whether it is rational A negative fraction is never rational An integer numerator over a zero denominator is never rational?
Statement 1 is true but totally unnecessary. As integer is always a rational and you do not need to convert it to a fraction to determine whether or not it is rational. A negative fraction is can be rational or irrational. The fact that it is negative is irrelevant to its rationality. An integer number over a zero denominator is not defined and so cannot be rational or irrational or anything. It just isn't.
Is it sometimes true when the product of Two rational numbers are rational?
No, it is always true.
Is -38 a rational number?
Yes, since it can be written as a ratio of two integers: 19/5
If the denominator of a fraction is rational then the fraction is rational?
That is not true.
Is is true the difference of two rational numbers is always negative?
No, it is not true.
When adding integers does a negative and a negative equal a positive?
No, that is not true.
When adding two rational numbers with different signs the sum will be zero Is this aways sometimes or never true?
sometimes true (when the rational numbers are the same)
This is a rational number negative 7 over 7?
TRUE

What is true about the product of two rational numbers?
It will be rational.
Is it sometimes true when the sum of two rational numbers are rational?
No, it is always true
Is it sometimes true when the product of Twp rational numbers are rational?
No, it is always true
Is it sometimes true when the product of Two rational numbers are rational?
No, it is always true.
Is it true that adding 1 to a number always increases it's absolute value?
No if its negative it lowers its absolute value.
Is it always true that two negatives make a positive?
Adding two negative numbers will always be negative. Subtracting two negative numbers may be positive or negative. Dividing or multiplying two negative numbers will always be positive.No
