You can put this solution on YOUR website!
"j" will stand for job or jobs, and "d" will stand for day or days.

His rate is 5%2F8 j per 10 d.  So his rate in j per d is

matrix%281%2C2%2C5%2F8%2Cj%29%2F%28matrix%281%2C2%2C10%2Cd%29%29 %22%22=%22%22 %28expr%285%2F8%29%2F10%29j%2Fd %22%22=%22%22 %28matrix%281%2C3%2Cexpr%285%2F8%29%2C%22%F7%22%2C10%29%29j%2Fd %22%22=%22%22 %28matrix%281%2C3%2Cexpr%285%2F8%29%2C%22%D7%22%2C1%2F10%29%29j%2Fd %22%22=%22%22 5%2F80j%2Fd %22%22=%22%22 1%2F16j%2Fd

or 1 job per 16 days.

So he can complete 1 job in 16 days.
