Algebra.Com's Answer #183969 by drk(1908)![]() ![]() ![]() You can put this solution on YOUR website! This question is about proportions. Let B = banana, C = coconut, F = fish and H = hammock.\r \n" ); document.write( "\n" ); document.write( "50B = 20C ; 30C = 12F. The least common multiple of 20 and 30 is 60. So,\r \n" ); document.write( "\n" ); document.write( "150B = 60C ; 60C = 24F. More succinctly, 150B = 24F.\r \n" ); document.write( "\n" ); document.write( "Now, 24F * 4 1/6 = 100F, so\r \n" ); document.write( "\n" ); document.write( "150(4 1/6)B = 625 B.\r \n" ); document.write( "\n" ); document.write( "So, it will take 625 bananas, or (B) \n" ); document.write( " |
