For example, 0 is an integer and whole number that is rational
Suppose x is a rational number and y is an irrational number.Let x + y = z, and assume that z is a rational number.The set of rational number is a group.This implies that since x is rational, -x is rational [invertibility].Then, since z and -x are rational, z - x must be rational [closure].But z - x = y which implies that y is rational.That contradicts the fact that y is an irrational number. The contradiction implies that the assumption [that z is rational] is incorrect.Thus, the sum of a rational number x and an irrational number y cannot be rational.
-0.3 is the ratio of -3 to 10, or 3 to -10, or 6 to -20, or -9 to 60, or 792 to -2,640 . Any one of these is enough to show that -0.3 is rational.

2.4 expressed as an improper fraction is 12/5 thus proving that it is a rational number
2.4 is a rational number because it can be expressed as an improper fraction in the form of 12/5
2.4 is a rational number because it can be expressed as an improper fraction in the form of 12/5
3.8 is a rational number because it can be expressed as a fraction in the form of 19/5 in its simplest form.
88 = 88/1. The number can be expressed as a ratio of two integers and, therefore, it is a rational number.
nothing at all!
Integers are counting numbers or include them. 1/2 is a rational number that is not a couinting number.
For example, 0 is an integer and whole number that is rational
Write it down. All terminating decimals are rational.
