Answer: Third Option is correct.
Explanation:
Since we have given that
In [tex]\frac{3}{4}[/tex] pound of a spice mix,
Number of cups of cinnamon is given by
[tex]\frac{5}{6}[/tex]
We need to find the number of cup of cinnamon per pound,
For this we will use "Unitary method" ,
So, for 1 pound,
Number of cups of cinnamon is given by
[tex]\frac{4}{3}\times\frac{5}{6}=\frac{10}{9}=1\frac{1}{9}[/tex]
[tex]\text{So, there are }1\frac{1}{9}\text{ cups the spice mix contain per pound.}[/tex]
Hence, Third Option is correct.
