$$\frac{4}{7}=\frac{x}{16}\\\\
\frac{4}{7}\times 16=x$$
$${\frac{{\mathtt{4}}}{{\mathtt{7}}}}{\mathtt{\,\times\,}}{\mathtt{16}} = {\frac{{\mathtt{64}}}{{\mathtt{7}}}} = {\mathtt{9.142\: \!857\: \!142\: \!857\: \!142\: \!9}}$$
so the answer is $$\frac{64}{7}=9\frac{1}{7}$$
The blank or the variable in the equation is 9.1..., but you should NEVER put decimals in a fraction.(That is like making a complex fraction.(We don't want that,now do we?))So the answer is 9.
