How do you decompose 57.9 times 23?

${\mathtt{57.9}} = {\mathtt{57}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{9}}}{{\mathtt{10}}}}$

So, break down 57.9, and distribute 23 across both coefficients.

${\mathtt{23}}{\mathtt{\,\times\,}}\left({\mathtt{57}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{9}}}{{\mathtt{10}}}}\right) = {\mathtt{X}}$

Solve for X. :)
