3 1/8 yd
3 7/8 yd

Respuesta :

1.

[tex]5\frac{3}{8}= \frac{43}{8}[/tex]

1c = 8 fl oz

[tex]\frac{43}{8}= \frac{43}{8}\times8=43[/tex]

Hence, a: 43 fl oz is correct

2.

1 inch = 0.0833 foot

43 inch = [tex]43\times0.0833=3.581[/tex]

Hence, option D [tex]3\frac{7}{12}[/tex] is correct.

3.

Length of material Mili has = [tex]7\frac{1}{2}= \frac{15}{2}[/tex]

Length needed for her skirt = [tex]4\frac{5}{8}= \frac{37}{8}[/tex]

Material left will be = [tex]\frac{15}{2}- \frac{37}{8}[/tex]

=[tex]\frac{60-37}{8}=\frac{23}{8}=2\frac{7}{8}[/tex]

Hence, option A is correct.
