7%2F%28+1%2F4%29.....you can write 7as 7%2F1
%287%2F1%29%2F%28+1%2F4%29....now we have dual fraction, and we can apply the rule:
When you divide two fractions, you take the reciprocal of the second fraction, or bottom fraction, and multiply. (Taking the reciprocal of a fraction means to flip it over.)

%287%2F1%29%2A%28+4%2F1%29=7%2A4%2F%281%2A1%29=7%2A4=28
