What is 1/4 minus 12?

Hey Ninja, after all that great effort aren't you going to change it back to a mixed numeral?

anyway I am going to take a differerent route. 

$$\frac{1}{4}-12\\\\ =\frac{1}{4}-11\frac{3}{4}-\frac{1}{4}\\\\ =-11\frac{3}{4}\\\\$$

$$12 can be written as $\frac{12}{1}$, so now we have:\\ $\frac{1}{4} - \frac{12}{1}$\\ The problem here is that we don't have a common demoninator. Let's multiply $\frac{12}{1}$ by $\frac{4}{4}$ to get a common denominator. \\ We can do this because $\frac{4}{4}$ is really the same thing as 1, and if you multiply any number by 1, you will get that original number.\\ For example, \\ $5\times 1 = 5$\\ $99\times 1 = 99$, etc...\\\\ So, let's multiply $\frac{12}{1}$ by $\frac{4}{4}$\\ $\frac{1}{4} - (\frac{12}{1}\times\frac{4}{4})\\\\ \frac{1}{4} - (\frac{48}{4})\\\\ -\frac{47}{4}$\\\\ And there we go! our answer is $-\frac{47}{4}$$ $
