Answer 1

2/8 x 6 = 3/2
9/8 x 2 = 9/4
9/4 - 3/2 = 3/4 lbs

Answer 2

Kim purchased 6 small containers of potato salad.Small containers weigh
`(2)/(8).lbs.`

Weight of Kim's purchase =6x
`(2)/(8) =(12)/(8).=(3)/(2). lbs`

Seth purchased 2 extra large containers of Potato salad.

Weight of extra large container=
`(9)/(8).lbs.`

Weight of Seth's purchase =2x
`(9)/(8). =(18)/(8).=(9)/(4).lbs`

Difference in weights of Seth and Kim =
`(9)/(4).-(3)/(2).=(3)/(4).lbs.`

Difference in weight =
`(3)/(4).lbs.`
