I don't know about a rate but this is the answer1
$${\frac{{\mathtt{1}}}{{\mathtt{4}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{9}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{16}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{25}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{36}}}} = {\frac{{\mathtt{1\,769}}}{{\mathtt{3\,600}}}} = {\mathtt{0.491\: \!388\: \!888\: \!888\: \!888\: \!9}}$$
I just copied you answer, opened the input=result box, pasted the question in, hit equal, and magic - there is your answer.
Did you try to do this on your android GoldenLeaf?
I don't know how to do almost anything on my android. Stupid thing. lol
