Question 1095729
<br>josmiceli's solution is valid; however, usually inverse proportion problems are solved with less work if you use the idea that the product of the two quantities is a constant.  So instead of doing
{{{156 = k/125}}}
to solve for the constant k, simply do
{{{156*125 = n*195}}}<br>
The solution to that equation is n=100; that means the number of tourists that left is 156-100 = 56.
