OpenStudy (igreen):

Set up a proportion. \(\sf\dfrac{3}{\dfrac{1}{6}} = \dfrac{x}{1}\)

OpenStudy (igreen):

Cross multiply and solve.

OpenStudy (igreen):

\(\sf 3 \times 1 =~?\) \(\sf \dfrac{1}{6} \times x=~?\)

OpenStudy (thadds2003):

1/2?

OpenStudy (br5ttany):

Its 18 oz I believe

OpenStudy (anonymous):

it is 18 oz. and let me explain why. It is because when you have 3 oz. and the jar is 1/6 full the full jar would have 18 oz. of seed. The equation would be 3 oz. x 6 = 18 oz. to check my answer and to clarify that this is correct I do 18 oz. divided by 6 which equals 3 oz. or what you can do is 18 x 1/6 which also equals 3. I hope this helps you and also can I have a medal?

OpenStudy (mathmale):

I'd approach this problem by writing an equation of ratios, and in doing so I'd be certain to compare apples to apples and oranges to oranges in my ratios. We're talking first about "a full jar" and "one sixth jar." I'd find the ratio of those two: \[\frac{ 1/6 }{ 1 }=\frac{ 1 }{ 6 }\] Next, I'd write another ratio comparing the given # of oz. of seed (3 oz.) to the unknown # of oz. of seed:\[\frac{ 3.oz }{x }\] Finally, equate these two ratios and solve the equation for x. Other approaches will succeed, but comparing likes to likes makes more sense.

OpenStudy (mathmale):

\[\frac{ \frac{ 1 }{ 6} }{ 1 }=\frac{ 1 }{ 6 }\]

OpenStudy (mathmale):

Therefore, \[\frac{ 1 }{ 6 }=\frac{ 3.oz }{ x }\]
