Question 1130342
.
<pre>
If I correctly understand your post, your task is to solve an equation


    {{{((4/5))/c}}} = {{{2/5}}}.


Multiply both sides by "c". You will get an equivalent equation


    {{{4/5}}} = {{{(2/5)*c}}}.


Multiply both sides by 5 to rid of the denominators. You will get


    4 = 2*c.


Last step is to divide both side by 2 to get the answer


    c = 2.
