to divide fraction do the following: [tex]3 \frac{5}{8} = \frac{(8 \times 3) + 5}{8} [/tex] simplify we get [tex] \frac{29}{8} [/tex] then to divide by 1/4 we need to flip it to 4/1 or just 4 [tex] \frac{29}{8} \div \frac{1}{4} = \frac{29}{8} \times \frac{4}{1} [/tex]
simplify and we get [tex] \frac{116}{8} [/tex] which equals 14.5 but you can't have half a person so the answer is: [tex]14 \: \: coworkers[/tex]
