Question 1143927
<br>
The ratio 6:5 means 6 girls for every 5 boys.<br>
So let the number of girls be 6x and the number of boys be 5x.  The difference between the number of boys and girls is then 6x-5x = x.<br>
But we are told that that difference is 3.<br>
So x = 3; that makes the number of girls 6x=18 and the number of boys 5x=15.<br.
But I can't answer your question, because you didn't bother to take the time to ask one....
