Is -7 a rational number?

Yes, -7 is indeed a rational number. By definition, a rational number is one that can be written as a simple fraction, that is, as a ratio of two integers. Since -7 can be expressed as -7/1, where both -7 and 1 are integers and 1 is not zero, it qualifies as rational.

Can -7 be expressed as a fraction?

Absolutely. Negative 7 can be expressed as a fraction. For instance, you can write it as -7/1, where the numerator is -7 and the denominator is 1. Both are integers, and the denominator is non-zero, fulfilling the criteria for a rational number. Many other fractional representations exist, like -14/2.

Why is negative seven considered rational?

Negative seven is considered rational because it precisely meets the mathematical definition. A number is rational if it can be written as a fraction p/q, where p and q are integers and q is not equal to zero. As -7 can be written as -7/1, with both -7 and 1 being integers, it perfectly fits...

Does negative seven fit the definition of a rational number?

Yes, negative seven absolutely fits the definition of a rational number. A rational number is defined as any number that can be expressed as the quotient or fraction p/q of two integers, where the denominator q is not equal to zero. Since -7 can be written as -7/1, it satisfies this condition.

Is the integer -7 also classified as a rational number?

Yes, the integer -7 is also classified as a rational number. The set of rational numbers includes all integers, because every integer 'n' can be expressed as the fraction n/1. Since -7 can be represented as -7/1, it clearly falls within the category of rational numbers.

How can we prove that -7 is a rational number?

We prove -7 is rational by demonstrating it fits the definition. A rational number can be written as p/q, where p and q are integers and q is not zero. We can express -7 as the fraction -7/1. Since -7 and 1 are both integers, and 1 is not zero, this confirms -7 is a...

What makes -7 a rational number in mathematics?

What makes -7 a rational number is its ability to be expressed as a ratio of two integers. Specifically, -7 can be written as -7 divided by 1, or -7/1. In this fraction, both the numerator (-7) and the denominator (1) are integers, and the denominator is not zero. This fulfills the exact requirements.

Can any negative integer, like -7, be rational?

Yes, any negative integer, like -7, can certainly be rational. All integers, whether positive, negative, or zero, are a subset of the rational numbers. This is because any integer 'x' can always be written as the fraction x/1, satisfying the criteria for being a rational number.

Is negative seven a member of the set of rational numbers?

Yes, negative seven is indeed a member of the set of rational numbers. The set of rational numbers, denoted by 'Q', encompasses all numbers that can be written as a fraction of two integers. Since -7 can be expressed as -7/1, it is explicitly included in this mathematical set.

Can any integer be classified as a rational number?

Yes, every integer can be classified as a rational number. Any integer 'n' can always be written as the fraction n/1. This precisely fits the definition of a rational number, which requires expression as p/q where p and q are integers and q is not zero. Thus, all integers are indeed a subset of rational...
