Algebra.Com's Answer #422575 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! If there are 30 children in a class and 3 are absent what is the percentage of absent children and what is the percentage of children present \n" ); document.write( " If you want to do %'s as ratios, then you can think of it as: \n" ); document.write( "part/total = %/100 \n" ); document.write( "In this case the part that is absent is 3 and the total is 30, so:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Multiply both sides by 100. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "The percent of students absent is 10%. That means that 100%-10%=90% were present.\r \n" ); document.write( "\n" ); document.write( "However, if you want practice. The number of students present is 30-3=27. So the proportion you would need to solve is. \n" ); document.write( " \n" ); document.write( "Reduce and multiply both sides by 100 to see if you get 90%.\r \n" ); document.write( "\n" ); document.write( "Happy Calculating!!! Hope that helped.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
