In your class 11 out of 25 students have brown hair. what percent have color other than brown? show work..

You can work this out two ways: 

1) you can find the percentage of students who have brown hair, and subtract from 100% to find the total percentage of other hair colors,

11 / 25 = 0.44 or 44% > 100% - 44% = 56% < this is the number of students without brown hair, 

or

2) you can find out the number of students who have a different hair color, and finding the percentage of that new number:

25 - 11 = 14 < this is the number of students in the class that have a hair color other than brown. To find the percentage:

14 / 25 = 0.56 or 56% 

 56% of students do NOT have brown hair.
