There is no such example. If you cannot use an exact fraction then there will not be an exact decimal that you can use instead. And, if you are using an approximate decimal, you could use an approximate fraction instead.
Divide the numerator by the denominator and express it as a decimal number (it may not be an exact number, so you may have to decide the number of decimal places). Examples: For the fraction 1/2, you would divide the numerator (1) by the denominator (2) and the answer turns out to be a decimal, exactly 0.5 For 5/8, the decimal is exactly 0.625 For 1/3, the decimal repeats, so it could be 0.33 or 0.3333 (repeats infinitely)
Exact same if there was no negative sign, the number is the number.
Since pi is irrational, there is (by definition) no way to express it as an exact fraction. Even so, many people write it as 22/7, which is a fairly accurate representation. But it is not exact!
Yes, because it isn't a decimal, nor a fraction.
Since pi is an irrational number it is impossible to represent the exact quantity as a decimal; you can only give and approximate value. However, if you write a fraction that includes the symbol for pi, you are giving an exact quantity.
An irrational number cannot be written as a fraction or to an exact decimal such as the symbol for pi or the square root of two. A rational number can be written in the form of a fraction or a decimal to an exact value.
It is said to be 22/7. And it is 3.14 in decimal form. * * * * * pi is a transcendental number which is a kind of irrational number. An irrational number cannot be represented as an exact fraction.
The number 0.083 is already written as a decimal and can therefore only be changed out of the decimal form.
an exact decimal must be with the number 0. in it or it is not exact.
If you mean the exact decimal 0.33333 then it is 33333/100000 If you mean the recurring decimal 0.33333... (that is the 3 repeats forever) then it is 1/3
