Select all of the rational numbers. (there can be more than one)

3^-1
square root of 12
square root of 9
-0.25
pi
0.6 (the six has a line over it)

Answer:

3^-1, square root of 9, -0.25, and 0.6

Step-by-step explanation:

Rational numbers are numbers that you can turn into fractions.

3^-1 = 0.3333333333... which is also known as 1/3

square root of 9 = 3, which can be written as 3/1

-0.25 can be written as -1/4

0.66666666... = 2/3

The numbers 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.

A number system is defined as a system of writing to express numbers.

The rational numbers are those that can be expressed as a ratio of two integers.

3⁻¹ = 1/3, which is a rational number.

sqrt(12) = sqrt(4 x 3) = 2sqrt(3), which is irrational.

sqrt(9) = 3, which is a rational number.

-0.25 = -1/4, which is a rational number.

pi is irrational.

0.6 = 3/5, which is a rational number.

Hence, 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.
