Question 886739

I would like to see the steps to solve this:  7/b+b/x/(2/b) when x=7 and b=4
<pre>
{{{7/b + (b/x)/(2/b)}}}_____{{{7/b + (b/x) * (b/2)}}}_____{{{7/4 + (4/7) * (4/2)}}}___{{{7/4 + (4/7) * 2}}}___{{{7/4 + 8/7}}}____{{{(49 + 32)/28}}}_____{{{highlight_green(highlight_green(81/28))}}}, or {{{highlight_green(highlight_green(2&25/28))}}}
