Bob and Tina ordered a pizza, but while Tina was changed her shirt, Bob at two-eighth of the pizza. When Tina come back she ate two-thirds of what was left. How much of the pizza did Tina eat?

Tina ate 2 slices of pizza

Step-by-step explanation:

If bob ate 2/8 of the pizza, there would be 6 slices left. If she then ate 2/3 when she got back, there would be 4 slices left and she would have eaten 2.

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

both equations and proportions are better.
