3. mi-li has 7 1/2 yd. of material. Her new skirt will take 4 5/8 yd. How much material will she have left after the skirt is made?
2 7/8 yd
2 1/8 yd >>>
3 1/8 yd
3 7/8 yd

Answer 1

1.

`5(3)/(8)= (43)/(8)`

1c = 8 fl oz

`(43)/(8)= (43)/(8)*8=43`

Hence, a: 43 fl oz is correct

2.

1 inch = 0.0833 foot

43 inch =
`43*0.0833=3.581`

Hence, option D
`3(7)/(12)` is correct.

3.

Length of material Mili has =
`7(1)/(2)= (15)/(2)`

Length needed for her skirt =
`4(5)/(8)= (37)/(8)`

Material left will be =
`(15)/(2)- (37)/(8)`

=
`(60-37)/(8)=(23)/(8)=2(7)/(8)`

Hence, option A is correct.
