Question 811771
hi there firstly to find percentage its always your score or value divided by the total score/value * 100:
{{{(70/95)*100 = 73.68%}}} are wearing red

to find the percent of students not wearing red two ways;
1) find the difference between the values you know then divide that new value by the total amount {{{95-70 = 25}}} {{{(25/95)*100 = 26.32%}}}
2) 100% - % of your first question {{{100-73.68 = 26.32%}}}

therefore:
number of students wearing red: ~74%
number of students not wearing red: ~26%
