If 6 men can do a piece of work in 14 days, how many men are needed to do the work in 21 days? Can you show me how to work it out?\r
\n" ); document.write( "\n" ); document.write( "Factors 21 and 14 have greatest common factor (GCF) of 7. Reducing fraction.
\n" ); document.write( "As we know; 6 men \"X\" work at 14 days
\n" ); document.write( " 9 men \"x\" work must be 21 days
\n" ); document.write( " the expression: 6 men 'X' work at 14 days
\n" ); document.write( " -----? 'x' work at 21 days
\n" ); document.write( " so that, we need to solve by how many men?
\n" ); document.write( " equation: 21*6/14
\n" ); document.write( " by Factors 21 and 14 have greatest common factor (GCF) of 7. Reducing fraction.
\n" ); document.write( " = 21*6/14
\n" ); document.write( " = 3*6/2
\n" ); document.write( " = 3*3/(1)note we can take out '1'
\n" ); document.write( " = 3*3
\n" ); document.write( " = 9 men
\n" ); document.write( " done! good luck!!
