Question 1115819
.
In {{{highlight(cross(20000))}}} <U>2000</U> a watch cost #2800. in 2008 the same watch cost #5200. give the 2000 cost to the 2008 cost as a ratio in its simplest terms.
~~~~~~~~~~~~~~~~~~~


<pre>
{{{2800/5200}}} = {{{28/52}}} = {{{(7*4)/(13*4)}}} = {{{7/13}}}.
</pre>

I am wondering - who is that "student" who can not solve it on his/her own ?


For whom I am doing it ?
