What is the rational number equivalent to 3 point 12 with a bar over 12?

slamgirl [31]

$\frac{12}{100}=0.12$

To get the 0.12 to repeat, the trick is to subtract 1 from the denominator

$\frac{12}{99}=0.12121212...$

Then reduce the fraction.

$\frac{12}{99}={4}{33}$

now add the 3 to get

$3.12121212.... = 3\frac{4}{33}$

Your friend claims that when a polynomial function has a leading coeffcient of 1 and the coefficients are all integers , every p

sammy [17]

Using the rational root theorem, it is found that your friend is correct.

<h3>What is the rational root theorem?</h3>

It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format $\frac{p}{q}$ .

In this problem:

The leading coefficient is 1, hence it's only factor is $q = 1$ , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.
