pam can build a house in 11 2/3 months and jerry can build a house in 8 3/4 months.
\n" ); document.write( "if they work together, how long would it take to build the house working together.
\n" ); document.write( ":
\n" ); document.write( "Convert 11 2/3 to \"35%2F3\"
\n" ); document.write( "Convert 8 3/4 to \"35%2F4\"
\n" ); document.write( ":
\n" ); document.write( "Let t = time required if they work together
\n" ); document.write( ":
\n" ); document.write( "Let the completed job = 1
\n" ); document.write( ":
\n" ); document.write( "A shared work equation:
\n" ); document.write( "\"t%2F%2835%2F3%29\" + \"t%2F%2835%2F4%29\" = 1
\n" ); document.write( "Invert the dividing fractions and multiply; you have:
\n" ); document.write( "\"%283t%29%2F35\" + \"%284t%29%2F35\" = 1
\n" ); document.write( "multiply by 35 to get rid of the denominators
\n" ); document.write( "3t + 4t = 35
\n" ); document.write( "7t = 35
\n" ); document.write( "t = \"35%2F7\"
\n" ); document.write( "t = 5 days working together
