Question

A scuba diver is 5 3/4 feet below the water surface, or −5 3/4 She dives downward another 3 1/2 feet. Subtract to find her depth in feet: −5 3/4−3 1/2=

Answer 1

-5 3/4 - 3 1/2

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

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

= -(8 + 3/4 + 2/4)

= -(8 + 5/4)

= -(8 + 1 1/4)

= - (9 1/4)

= - 9 1/4 ft


So her depth in feet is 9 1/4 feet.

Answer 2

`-5 (3)/(4)` =
`(-23)/(4)`
3
`(1)/(2)` = [ tex] \frac{7}{2} [/tex] =
`(14)/(4)`


`(-23)/(4)`-
`(14)/(4)` =
`(-37)/(4)`=-19.25 feet
