ANSWER

EXPLANATION
It was given that,a bottle of la belle bœuf contains 3/8 ounces of perfume.
We want to find how many ounces of perfume would 4 1/2 bottles contain.
If 1 bottle contains 3/8 ounces;
Then 4½ bottles should contain more ounces.
If more less divides.
4½ bottles contain


=1.6875 ounces.
The answer is B because the slope is always the one multiplying the x and the 1 is negative because the equation is y-y1=m(x-x1)
When you have ratios, and some unknowns, you can create complex fractions from them. Bring them to the same denominator, and solve for x.
Example - we have this proportion:
2-x
5-45
And we can change it into fraction:
\frac{2}{5}=\frac{x}{45}
\frac{2*9}{5*9}=\frac{x}{45}
\frac{18}{45}=\frac{x}{45}
18=x
In case of more complex fractions it may come in handy.
