(Express each ratio in lowest terms)
2/3 : 22/9

3/11

Step-by-step explanation:

You have to divide the factors, so you would multiply 2 times 9 over 3 times 22.  When you multiply them together you get 18 over 66. If you simplify that then you would get 3/11

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

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
