Algebra.Com's Answer #772066 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "What fraction of the animals in the store are birds and bunnies? \n" ); document.write( "There are no animals in the store that are both birds and bunnies; so the answer is 0. \n" ); document.write( "What fraction of the animals in the store are not birds and bunnies? \n" ); document.write( "ALL of them are not both birds and bunnies; so the answer is 1. \n" ); document.write( "Now let's ask and answer the right questions. \n" ); document.write( "What fraction of the animals in the store are birds OR bunnies? \n" ); document.write( "birds 2/5; bunnies 3/8. Get a common denominator: 5*8 = 40. \n" ); document.write( "birds 16/40; bunnies 15/40 \n" ); document.write( "birds OR bunnies: 16/40+15/40 = 31/40 \n" ); document.write( "What fraction of the animals in the store are not birds OR bunnies? \n" ); document.write( "1-31/40 = 9/40 \n" ); document.write( " \n" ); document.write( " |
