5 1/2 x 4 3/8

Hallo anonymous!

5 1/2 x 4 3/8 = 11/2 * 35/8 = 385/16 = 24 1/16

:- )

(5+1/2) * (4+3/8) = 11/2 * 35/8 =

$$\left({\frac{{\mathtt{11}}}{{\mathtt{2}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{35}}}{{\mathtt{8}}}}\right) = {\frac{{\mathtt{385}}}{{\mathtt{16}}}} = {\mathtt{24.062\: \!5}}$$

$$\left({\mathtt{5}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right){\mathtt{\,\times\,}}\left({\mathtt{4}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{3}}}{{\mathtt{8}}}}\right) = {\frac{{\mathtt{385}}}{{\mathtt{16}}}} = {\mathtt{24.062\: \!5}}$$
