Is 2.141414 a rational number?
Yes, 2.141414 is a rational number. A rational number is a number that can be expressed as a fraction, where the numerator and denominator are both integers. 2.141414 can be expressed as the fraction 2141414/1000000, which is a valid example of a rational number.
Rational numbers can also be expressed as a terminating or repeating decimal. In this case, 2.141414 can be expressed as a repeating decimal, where the digits 141414 are repeated infinitely.
Is 43.123456789 rational?
Yes, 43.123456789 is a rational number. A rational number is a number that can be expressed as a fraction, a/b, where a and b are integers and b is not equal to 0. 43.123456789 can be expressed as the fraction 43123456789/10000000, which is a fraction with two integers.
Therefore, 43.123456789 is a rational number.
How do you know if pi is irrational?
Pi is an irrational number, meaning it cannot be written as a fraction, as it has an infinite number of digits that can never settle into a repeating pattern. To be sure that pi is irrational, one can use a proof offered by mathematician Johann Lambert in 1767.
This proof states that since the area of a circle is pi multiplied by the square of the radius, and the area of the circle is an irrational number, it follows that pi must be irrational also. Additionally, as pi is defined as the ratio between the circumference and diameter of a circle, and the ratio between two incommensurable lengths is known to be irrational, this further supports the fact that pi is irrational.
What is a rational number between 3.14 and pi?
A rational number between 3.14 and pi is 3.15. This is because pi is an irrational number, meaning it cannot be expressed as a fraction or decimal and cannot be written as a finite or repeating decimal.
Pi is equal to the ratio of a circle’s circumference to its diameter, but is approximate as an irrational number and is often rounded to 3.14. Rational numbers on the other hand, like 3.15, can be expressed as a fraction or decimal.
