Algebra.Com's Answer #537135 by JulietG(1812) You can put this solution on YOUR website! If you have 40 and you add 5, you now have 45 students. 4:5 is 9. 45/9 = 5. Your new ratio is 4:5 or 20 girls:25 boys. \n" ); document.write( "Your previous ratio was 2:3 (5 total). 40/5 = 8 \n" ); document.write( "Previously there were 8*2 girls: 8*3 boys, or 16:24. \n" ); document.write( "To get from the old ratio to the new one you added 4 girls and one boy. \n" ); document.write( " |
