Which of the following numbers is irrational?

a fraction with numerator negative 9 and denominator 5, a fraction with numerator square root of 5, a fraction with numerator 7 and denominator 3, square root of 9

a fraction with numerator negative 9 and denominator 5
square root of 5
a fraction with numerator 7 and denominator 3
square root of 9

The answer to your question would be : B, square root of 5. The reason for this is because the square root of 5 will result in a number that can't really ever be exact. Like it will be 2.. (the Xs represent random numbers). If you look at A, that is just -9/5, which is -1.8 in decimal form. Look at C, that is 7/3, which is 2.3 repeating, and D is just 3. Therefore your answer is B.
