how do you do 4/9-1/12?

Good answer

First, put everything in improper fraction...

1-1/2 = 3/2...so...

$${\frac{{\mathtt{4}}}{{\mathtt{9}}}}{\mathtt{\,-\,}}{\frac{{\mathtt{3}}}{{\mathtt{2}}}}$$

Find the common denominator (which is 18)... and then find the numerators...

$${\frac{{\mathtt{4}}}{{\mathtt{9}}}}{\mathtt{\,-\,}}{\frac{{\mathtt{3}}}{{\mathtt{2}}}} = {\frac{{\mathtt{8}}}{{\mathtt{18}}}}{\mathtt{\,-\,}}{\frac{{\mathtt{27}}}{{\mathtt{18}}}}$$

Then you subtract the numerators (8 - 27)...

$${\frac{{\mathtt{8}}}{{\mathtt{18}}}}{\mathtt{\,-\,}}{\frac{{\mathtt{27}}}{{\mathtt{18}}}} = {\mathtt{\,-\,}}{\frac{{\mathtt{19}}}{{\mathtt{18}}}}$$

Hope this helps...

Thanks, happy 7!
