Percentage question

24534 attendees who supported queensland!

First of all, let's figure out the percent that were not NSW supporters. To do this, subtract 71% from 100%:

$100\%-71\%=29\%$

29% of people supported queensland. To find the amount of people who supported queensland, multiple the number of attendees by the percent:

$84600*29\%$

$=\frac{84600}{1}*\frac{29}{100}$      Here, I converted the percent to a fraction.

$=\frac{84600*29}{100}$

$=\frac{2453400}{100}=24534$ attendees who supported queensland!
