Yesterday, there were 60 problems assigned for math homework. Adele got 12 problems correct and 48 problems incorrect. What percentage did Adele
get correct?

20%

Step-by-step explanation:

12 ÷ 60 = 0.2

0.2 x 100 (to make the percent form) = 20

20%

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
