A rational number is a fraction that includes all integers except for when zero is the divisor. This means that a rational number can be expressed as a quotient of two integers, where the numerator is an integer and the denominator is a non-zero integer.

Answer

Which of the following is a rational number?(1 point) Responses 7–√ square root of 7 7.8 7.8 88√ the fraction with numerator 8 and denominator square root of 8 π

GPT-4o mini · Answer

Among the given options, the rational number is 7.8.

To clarify the other options:

$7 - \sqrt{7}$ is not necessarily rational since $\sqrt{7}$ is an irrational number, making the entire expression irrational.
$88 \sqrt{8}$ , where $\sqrt{8}$ is also irrational, means the product is irrational.
$π$ is a well-known irrational number.

Rational numbers can be expressed as fractions where both the numerator and denominator are integers (with the denominator not being zero). Since $7.8$ can be expressed as $\frac{78}{10}$ or $\frac{39}{5}$ , it is a rational number.
