eimsori [14]3 years ago
4 0

Answer:

<u>The correct answer is D. π</u>

Step-by-step explanation:

Let's recall that rational numbers are those that can be written as a ratio or fraction of two integers. Quite the opposite, irrational numbers can't be written as a ratio or fraction of two integers.

Upon saying that we have:

A. A fraction with numerator negative 15 and denominator 4 is a rational number because we can represent it: -15/4

B. A fraction with numerator negative 7 and denominator 9 is a rational number because we can represent it: -7/9

C. √4 is a rational number because we can represent it: 2 or 2/1

D. π is the most known irrational number because we can't represent it as a ratio or fraction: 3.14159265358979....and more can't be written as a ratio or fraction.

<u>The correct answer is D. π</u>
