So if Jacob works x shifts, he works for a total of \(2 \frac{1}{2}\) hours, and each shift is \(\frac{3}{4}\) hours, the equation can be set up as;
\(2 \frac{1}{2} =x* \frac{3}{4} \\( \frac{4}{3} )*2 \frac{1}{2} =(x* \frac{3}{4})*( \frac{4}{3} )\\ \frac{4}{3} * \frac{5}{2} =x\\x= \frac{20}{6} =3 \frac{1}{3}\)
So Jacob worked \(3 \frac{1}{3}\)shifts
