2/5=x-2/20
\n" ); document.write( "I started by multiplying 5 through the problem:
\n" ); document.write( "(5)(2/5)=(5)(x-2/20) and got: 2=5x-10/100!
\n" ); document.write( "You should have gotten:
\n" ); document.write( "2=5x-10/20 because the \"5\" multiplies the 2 but not the 20.
\n" ); document.write( "Then:
\n" ); document.write( "2=5x-(1/2)
\n" ); document.write( "Multiply thru by 2 to get:
\n" ); document.write( "4=10x-1
\n" ); document.write( "10x=5
\n" ); document.write( "x=1/2
\n" ); document.write( "Comment:
\n" ); document.write( "The Least Common Denominator of your original problem
\n" ); document.write( "was 20. You should have multiplied both sides by 20
\n" ); document.write( "to clear away all denominators, as follows:
\n" ); document.write( "20(2/5)=20(x-2/20)
\n" ); document.write( "8=20x-2
\n" ); document.write( "20x=10
\n" ); document.write( "x=1/2
