| Algebra.Com's Answer #27558 by jmg(22)      You can put this solution on YOUR website! If you have multiple choice problems I always work the problems by eliminating wrong answers. \r \n" ); document.write( "\n" ); document.write( "You should automatically be able to eliminate b. You should know that 2/5 is not equal to 5/2. \r \n" ); document.write( "\n" ); document.write( "You should also be able to automatically eliminate A and D. Both of those numbers have a whole number of 2 attached to them. \r \n" ); document.write( "\n" ); document.write( "You should know that 2/5 will never be bigger than 1. If you only have 2/5 then you definitely don't have 5/5, which would equal 1, so you definitely don't have 2. \r \n" ); document.write( "\n" ); document.write( "That leaves answer choice B. \n" ); document.write( "You can show that 2/5 = 0.4 in one of two ways: \n" ); document.write( " Calculator (if you are allowed to use one): Divide the top \n" ); document.write( " number by the bottom number. 2/5 = 0.4 \n" ); document.write( " If you can't use a calculator. Then change 2/5 to a number out of 100. \n" ); document.write( " 2/5 = 40/100 \n" ); document.write( " 40/100 = 40% = 0.4 or 0.40 \n" ); document.write( "Hope this helps. \r \n" ); document.write( "\n" ); document.write( " \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
