Algebra.Com's Answer #620205 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! We can set up the proportion: \n" ); document.write( "(2 1/4)/(1/12) = x / (1 3/4) \n" ); document.write( "and solve for x... \n" ); document.write( "What is probably easier than cross-multiplying is just to divide 2 1/4 by 1/12... \n" ); document.write( "We get \n" ); document.write( "2 1/4 / 1/12 = 27 \n" ); document.write( "and then multiply this by 1 3/4 and get \n" ); document.write( "27 x 1 3/4 = 27 x 7/4 = 189/4 = 47 1/4 cups flour\r \n" ); document.write( "\n" ); document.write( "This may not be what you think because you give 1/12 cup of sugar...you may mean 1 1/2 cup sugar...please resubmit... \n" ); document.write( " |
