What is the definition of rational approximation?

example the rational approximation of pi is 3.14 so a rational approximation is shortening a really long number so it can be written out


Is 3.14159 a rational or irrational number?

3.14159 is rational. However, it is often used as an approximation for π, which is irrational. It is important to recognise that the rational number, 3.14159, is only an approximation for π.

The square root of six is irrational. Do you mean a rational approximation?


What is the rational approximation of pi?

3.14159 is acurate enough for most applications.


Is 3.14 an irrational number a rational number or an integer?

3.14 is rational. However, it is often used as an approximation for pi, which is irrational.


Is 3.40764076407640764076 an rational number or irrational?

As a terminating decimal 3.40764076407640764076 = 340764076407640764076/100000000000000000000 which is a rational number As an approximation to the recurring decimal 3.4076... = 34073/9999 which is a rational number. So either way, it is a rational number.


What is the decimal approximation of 9.6 to keep it a rational number?

It is already a decimal and a rational number because it can be expressed as fraction in the form of 48/5 simplified

What is the sq root of pi?

square root(pi) is about 1.77245385. It is not a rational number so this is just an approximation.


When do you need to approximate an irrational number with a rational value?

If the simplified form of an expression contains an irrational number and a numerical evaluation is required then it is necessary to use a rational approximation.


Is 2 times 3.14 a rational Number?

Yes. 2 x 3.14 = 6.28 = 6 7/25 = 157/25 which is rational. If you are using 3.14 as an approximation to {pi}, then 2 x {pi} is not rational.
