four over five plus open bracket three three over five multiplied by seven over 18 close bracket minus zero point two

Enter this into the calculator and hope it's the answer to your rather wordy question:)

4/5 + (3/5 * 7/18) -0.2

$${\frac{{\mathtt{4}}}{{\mathtt{5}}}}{\mathtt{\,\small\textbf+\,}}\left({\frac{{\frac{{\mathtt{3}}}{{\mathtt{5}}}}{\mathtt{\,\times\,}}{\mathtt{7}}}{{\mathtt{18}}}}\right){\mathtt{\,-\,}}{\mathtt{0.2}} = {\frac{{\mathtt{5}}}{{\mathtt{6}}}} = {\mathtt{0.833\: \!333\: \!333\: \!333\: \!333\: \!3}}$$
