0.5, 1 1/ 4, 0.25, 3/ 8

Are you supposed to change decimals to fractions and fractions to decimals?

If yes,

0.5 = 1/2

11/4 = 2.75

0.25 = 1/4

3/8 = 0.375

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

hope this you
