Answer:
15:12:3= 15 boys 12 girls and 3 teachers
Step-by-step explanation:
There are 5 boys in the School and 4 girls in the School and 1 teachers in the School
Because you got to try to look for a number that you can divide by all three numbers. And that number is 3. Because if you do 15 ÷ 3 =5, 12÷3=4, 3÷3=1
