# How to place limit values on the top and bottom of summation in a fraction

I am trying to write the upper and lower limits on the summation symbol in this equation as

$Average~accuracy =\displaystyle \frac{\sum_{i=1}^{6}{Accuracy_i}}{i}=94.45\%$


or

$Average~accuracy =\displaystyle \frac{\sum_{i=1}^{6}{Accuracy_i}}{i}=94.45\%$


But both are printing the limits at the edges. Is there any way to print them at the top and bottom as we write them with pen and paper?

\documentclass{article}
$\text{Average accuracy} = \frac{\displaystyle\sum_{i=1}^{6}{\text{Accuracy}_i}}{i}=94.45\%$
$\text{Average accuracy} = \frac{\sum\limits_{i=1}^{6}{\text{Accuracy}_i}}{i}=94.45\%$
