Question

I don't understand help!

Answer 1

So if Jacob works x shifts, he works for a total of
`2 (1)/(2)` hours, and each shift is
`(3)/(4)` hours, the equation can be set up as;

`2 (1)/(2) =x* (3)/(4) \\( (4)/(3) )*2 (1)/(2) =(x* (3)/(4))*( (4)/(3) )\\ (4)/(3) * (5)/(2) =x\\x= (20)/(6) =3 (1)/(3)`
So Jacob worked
`3 (1)/(3)`shifts
