How do i find x to solve the the proportion?

So firstly, cross-multiply the proportion:

Next, divide both sides by 63:

Next, we need to simplify the fraction. To do this, we need to divide both the numerator and the denominator by their GCF, or greatest common factor. In this case, their GCF is 7:

In short, x = 8/9

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal
