Question 1078587

A paroxysm of laughter escaped a few. If the ratio of the laughers to the solid was 2:17, and 7600 were in the throng, how many did not laugh? I tried dividing everything in half, but that didn't work, so I need a little help, please. Thank you!
<pre>Fraction that laughed: {{{matrix(1,3, 2/(2 + 17), "=", 2/19)}}}
Fraction that DID NOT laugh: {{{matrix(1,3, 17/(2 + 17), "=", 17/19)}}}
Number that DID NOT laugh: {{{highlight_green(matrix(1,5, 17/19, "*", "7,600", "=", "6,800"))}}}
