Which of the following is a rational number: 2π, 6/0, 61−−√, or 0.37815?(1 point)
The rational numbers are numbers that can be expressed as a ratio of two integers.
Out of the options given:
- 2π is an irrational number because π is an irrational number.
- 6/0 is undefined because division by zero is undefined.
- 61−−√ is an irrational number because the square root of 61 is irrational.
- 0.37815 is a rational number because it can be expressed as the fraction 37815/100000.
Therefore, the rational number from the given options is 0.37815.
A rational number is a number that can be expressed as a fraction, where the numerator and denominator are integers.
Out of the options given:
- 2π is an irrational number because π is an irrational number.
- 6/0 is undefined because you cannot divide by zero.
- 61−−√ is likely an irrational number since square roots of most numbers are irrational, but without the numerical value, we cannot determine for certain.
- 0.37815 is a rational number because it can be expressed as a fraction (e.g., 37815/100000).
Therefore, the rational number in the given options is 0.37815.
