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 a negative integer a rational number?
Absolutely. As long as it can be expressed as a fraction with the denominator not being zero, and both numerator and denominator being integers.
What is a rational exponent in math?
If the exponent or raised power of a number is in the form of p/q the exponent is said to be rational exponent. For example= 11/2 22/3
In rational functions what happens when w gets close to zero?
The answer depends on what w represents. If w is the denominator of the rational function then as w gets close to zero, the rational function tends toward plus or minus infinity - depending on the signs of the dominant terms in the numerator and denominator.
Why is negative 8 a rational number?
Any whole number can be written as a fraction, with the whole number in the numerator, and the number one in the denominator. Compare this to the definition of "rational number".
How can a rational number be positive?
A rational number is simply a number that can be expressed as a fraction, with integer numerator and denominator. Such a number can be positive, negative, or zero.A rational number is simply a number that can be expressed as a fraction, with integer numerator and denominator.

Is -15 rational or irrational?
Any integer, whether positive or negative, is a rational number. It can be expressed as a fraction with a negative numerator and a denominator of 1.
Why is -6 rational?
All integers, including negative integers, are rational. They can all be expressed as a fraction with the denominator 1.
How do you simplify numbers when they have a negative rational exponent?
A negative exponent is simply the reciprocal.A rational exponent of the form p/q is the qth root of the pth power.So for example,x^(-2/3) = 1/x^(2/3) = 1/cuberoot(x^2) or, equivalently, 1/[cuberoot(x)]^2
Negative fractions are Rational number?
They are rational, if the numerator and denominator are integers. For example, -2 / 3 would be a rational number.They are rational, if the numerator and denominator are integers. For example, -2 / 3 would be a rational number.They are rational, if the numerator and denominator are integers.

When subtracting rational expressions with a common denominator always remember to the negative sign?
Distribute

Distinguish between a pole and an essential singularity?
If the Laurent series has only finitely many terms with negative powers of z - c, then the singularity is a pole. The biggest negative exponent is the order of the pole. Example: Singularities of rational functions with no common factors in its numerator and denominator. (These come from setting the denominator equal to 0.) If the Laurent series has infinitely many terms with negative powers of z - c, then the singularity is essential. Example: e^(1/z) = 1 + (1/z) + (1/2!) 1/z^2 + ... has an essential singularity at z = 0.
Is a negative integer a rational number?
Absolutely. As long as it can be expressed as a fraction with the denominator not being zero, and both numerator and denominator being integers.

Can a rational number be negative in the denominator?
Yes. It can also be negative in the numerator. Both positive and negative numbers (as well as zero) can be rational numbers. Both positive and negative numbers can be irrational numbers. Both positive and negative numbers (as well as zero) can be integers.
