Answer:
30
Step-by-step explanation:
8 plus 12 is 20
20 divided my 4 is 5
5 plus 5 is 10
6 minus 3 is 3
10(from the first half) times 3(from the second half) is 30
1:3 is the ratio to boys and girls. I know that 1/4 must be girls. 3/4 will be boys.
Divide 236 by 4.
236/4= 59
Multiply that by 3.
59*3= 177
177 of the students are boys.
I hope this helps!
