Yes, 3.2 is a rational number because it can be expressed as the fraction 32/10, which simplifies to 16/5. Rational numbers are defined as numbers that can be represented as the quotient of two integers, and since 3.2 meets this criterion, it is considered rational.

Is 0.323232 a rational number?

A rational number is one which can be expressed by a division of a/b where both a and b are integers. In this case, we have a repeating decimal. All repeating decimals are rational numbers, and so we can say 0.323232.... is a rational number. The proof is as follows: 0.323232... x 100 = 32.323232... 0.323232... x 100 - 0.323232.... = 32 0.323232... x 99 = 32 0.323232... = 32/99 Thus 0.323232.... can be expressed as the fraction 32/99, and so is rational.


Is this a rational number 0.323232?

A rational number is a number that can be expressed as the division a/b where a and b are both integers. In this case 0.323232.... is a recurring decimal, and so is rational, as all recurring decimals are rational. This can be proved in the following way: 0.323232... x 100 = 32.323232... 0.323232... x 100 - 0.323232... = 32 0.323232... x 99 = 32 0.323232... = 32/99 Therefore 0.323232... is a rational number.
