Question

Find the sum or difference of the following:

$\frac{8}{9}-\frac{6}{12}$

Answer 1

Simplify the given expression by taking L.C.M:

So,

$$\begin{gathered} \frac{8}{9}-\frac{6}{12} \\ =\frac{8\times 12}{9\times 12}-\frac{6\times 9}{12\times 9} \\ =\frac{96}{108}-\frac{54}{108} \\ =\frac{96-54}{108} \\ =\frac{42}{108} \\ =\frac{21}{54} \\ =\frac{7}{18} \end{gathered}$$

Hence, the Difference is $\frac{7}{18}$.
