A fish was swimming 3 1/2 feet below the water's surface at 7:00 a.m. Four hours later, the fish was at depth that is 5 1/4 feet below where it was at 7:00 a.m. What rational number represents the position of the fish with respect to the water's surface at 11:00 a.m.?

Answer 1

`(35)/(4)` feet below the surface

adding the 2 quantities

3
`(1)/(2)` + 5
`(1)/(4)`

= (3 + 5 ) + (
`(1)/(2)` +
`(1)/(4)`)

= 8 + (
`(2)/(4)` +
`(1)/(4)`)

= 8 +
`(3)/(4)` = 8
`(3)/(4)` =
`(35)/(4)`
