Identify the measures of the angles below.

So,

One-eighth gallon of water will fill two-thirds of the bin.

We want the sentence: "x gallons of water will fill three-thirds of the bin."

What we do is multiply two-thirds by its reciprocal (three-halves) and make sure we do it on both sides.

\frac{1}{8} = \frac{2}{3} x

\frac{3}{2} * \frac{1}{8} = x

\frac{3}{16}\ gal. = x

So your equation would look like this:

\frac{1}{8} * \frac{3}{2}\ gal._{water} = x
