The rate that the job is getting done by thge 10 men and 15 women
\n" ); document.write( "is 1 job / 6 days. I'll say that the rate that 1 man is doing the job
\n" ); document.write( "is \"1%2Fm\" jobs/day and the rate that 1 woman is doing the job is
\n" ); document.write( "\"1%2Fw\" jobs/day.
\n" ); document.write( "10 men are working 10 times as fast and 15 women are working 15 times
\n" ); document.write( "as fast.
\n" ); document.write( "So, the rate 10 men are working is \"10%2A%281%2Fm%29\". The rate that
\n" ); document.write( "15 women are working is \"15%2A%281%2Fw%29\" therefore
\n" ); document.write( "\"1%2F6+=+10%2A%281%2Fm%29+%2B+15%2A%281%2Fw%29\"
\n" ); document.write( "The problem tells me that 1 man does the job in 100 days, so
\n" ); document.write( "\"1%2Fm+=+1%2F100\"
\n" ); document.write( "\"1%2F6+=+10%2A%281%2F100%29+%2B+15%2A%281%2Fw%29\"
\n" ); document.write( "\"1%2F6+=+1%2F10+%2B+15%2Fw\"
\n" ); document.write( "multiply both sides by the LCD, 30w
\n" ); document.write( "\"5w+=+3w+%2B+30%2A15\"
\n" ); document.write( "\"2w+=+450\"
\n" ); document.write( "\"w+=+225\"
\n" ); document.write( "So, \"1%2Fw+=+1%2F225\". It takes 1 woman 225 days to do the job alone.
\n" ); document.write( "check
\n" ); document.write( "\"1%2F6+=+10%2A%281%2F100%29+%2B+15%2A%281%2F225%29\"
\n" ); document.write( "\"1%2F6+=+1%2F10+%2B+1%2F15\"
\n" ); document.write( "\"5%2F30+=+3%2F30+%2B+2%2F30\"
\n" ); document.write( "OK\r
