Part 3)
we know that
[tex]1\ pint=2\ cup[/tex]
by proportion
[tex]\frac{2}{1} \frac{cup}{pint} =\frac{x}{9} \frac{cup}{pint}\\ \\x=9*2\\ \\x=18\ cup[/tex]
therefore
the answer Part 3) is the option A
[tex]18\ cup[/tex]
Part 4)
we know that
[tex]1\ Kg=1,000\ grams[/tex]
by proportion
[tex]\frac{1}{1,000} \frac{Kg}{grams} =\frac{x}{3,070}\frac{Kg}{grams}\\ \\x*1,000=3,070\\ \\x=3.07\ Kg[/tex]
therefore
the answer Part 4) is the option A
[tex]3.07\ Kg[/tex]
