The salad recipe needs $\frac{1}{4}$ cups of vinegar for every $\frac{2}{3}$ cup of oil.

Now we multiply both by 4

We get

The salad recipe needs $4(\frac{1}{4}) = 1$ cup of vinegar for $4 (\frac{2}{3} ) =\frac{8}{3}$ cups of oil.

But $\frac{8}{3} = 2\frac{2}{3}$

So for every 1 cup of vinegar we need $2\frac{2}{3}$ cups of oil
