How do I make a fraction on this online calculator ? Or does it have no fraction key ?
+118613 sorry no fraction key
2 thirds would go in as 2÷3
5 and 3/4 take away 9 and 7/8
(5+3÷4)-(9+7÷8)=
I hope that helps. 
$$\left({\mathtt{5}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{3}}}{{\mathtt{4}}}}\right){\mathtt{\,-\,}}\left({\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{7}}}{{\mathtt{8}}}}\right) = -{\mathtt{4.125}}$$
