One grocery clerk can stock a shelf in 30 minutes, wheras a second clerk requires 45 minutes to do the same job. If the two clerks worked together, how many minutes would it take to stock the shelf?\r
\n" ); document.write( "\n" ); document.write( "First clerk's work rate: 1/30
\n" ); document.write( "Second clerk's work rate: 1/45
\n" ); document.write( "x=the amount of time they can do it together.
\n" ); document.write( "Together the work rate: 1/x
\n" ); document.write( "\"1%2F30%2B1%2F45=1%2Fx\" the LCD is:90x Multiply both sides of the equal sign by that and clear your fractions.
\n" ); document.write( "\"90x%281%2F30%2B1%2F45%29=90x%281%2Fx%29\"
\n" ); document.write( "\"90x%2F30%2B90x%2F45=90x%2Fx\"
\n" ); document.write( "\"3x%2B2x=90\"
\n" ); document.write( "\"5x=90\"
\n" ); document.write( "\"5x%2F5=90%2F5\"
\n" ); document.write( "\"x=18\"
\n" ); document.write( "It would take the two 18 minutes to do it together.
