You can put this solution on YOUR website!
All of his time (as a decimal) is 100%=1.00
\n" ); document.write( "As a fraction this is 1/1=1.
\n" ); document.write( "To work out the time left, subtract the time spent from one:
\n" ); document.write( "\"timeleft=1-1%2F3-2%2F7\"
\n" ); document.write( "this can be done fairly easily with a calculator, but if you don't have one handy you need to get rid of the denominators.
\n" ); document.write( "Let
\n" ); document.write( "t = time left
\n" ); document.write( "\"t=1-1%2F3-2%2F7\"
\n" ); document.write( "multiply by the denominators to eliminate the fractions:
\n" ); document.write( "\"3t=3-1-6%2F7\"
\n" ); document.write( "\"21t=21-7-6\"
\n" ); document.write( "\"21t=8\"
\n" ); document.write( "Now \"t=8%2F21\"\r
\n" ); document.write( "\n" ); document.write( "I hope this helps.
\n" ); document.write( "P.S. I am trying to start up my own homework help website. I would be extremely grateful if you would e-mail me some feedback on the help you received to adam.chapman@student.manchester.ac.uk
