Answer:
Red=3
Brown=12
Explanation:
So to find 1/6 of 18 you divide 18 by 6 which is 3.
red = 3
Then to find 4/6 well you've already found out 1/6 is 3 so all you need to do is times that by 4.
3x4=12
Brown = 12
3 students with red hair
12 students with brown hair
1/6 times 18 = 18/6 = 3 students with red hair
4/6 times 18 = (18 times 4)/6= 12 students with brown hair
