Answer:
There are 12 boys in the classroom.
Step-by-step explanation:
I turned it into an expression from 3:2 to 3x + 2x = 20. The 20 representing the overall students.
Next, combine the terms,
3x + 2x = 20.
5x = 20.
Then 20 divided by 5x is equal to 4.
Now, we plug in the 4 to the missing number which is x.
3(4) + 2(4) = 20
Lastly, you multiply 3 x 4 = 12 and 2 x 4 = 8.
The Boys Number: 12
The Girls Number: 8
Since we are looking for how many boys, the number 12 is your clear and final answer.
