Algebra.Com's Answer #409137 by Shana-D77(132)![]() ![]() You can put this solution on YOUR website! The 5 in \"3:5\" means 5 parts. Boys to girls = boys:girls. Then the 3 represents boys and the 5 is girls.\r \n" ); document.write( "\n" ); document.write( "They tell you there are 275 girls. So, the 5 represents 275 girls. If 5 parts = 275 then 1 part = 275/5 = 55 girls. 1 unit = 55. \r \n" ); document.write( "\n" ); document.write( "There are 3:5 boys. So there are 3x55 boys or 165 boys. \n" ); document.write( " |
