The number 121 is a rational number if 121 can be expressed as a ratio, as in RATIOnal. A quotient is the result you get when you divide one number by another number. For 121 to be a rational number, the quotient of two integers must equal 121.

## Is 0 a real number?

Real numbers consist of zero (0), the positive and negative integers (-3, -1, 2, 4), and all the fractional and decimal values in between (0.4, 3.1415927, 1/2). Real numbers are divided into rational and irrational numbers. ), it is rational.

## Is 32 rational or irrational?

In the same way we saw that only the square roots of square numbers are rational, we could prove that only the nth roots of nth powers are rational. Thus, the 5th root of 32 is rational because 32 is a 5th power, namely the 5th power of 2. But the 5th root of 33 is irrational.
