The square below represents one whole express the shaded area as a fraction a decimal and a percent of the whole

1).

2). 0.81

3). 81%

Step-by-step explanation:

There are total 10×10 = 100 squares in the picture and number of shaded squares = 100 - 19 = 81

Shaded area expressed as the fraction of the whole =

Shaded area in decimals of the whole =

Shaded area in percent of the whole = = 81%

The fraction, decimal, and percentage form for the shaded squares will be , 0.81, and 81%, respectively.

From the given figure of squares, it can be concluded that:

Now, the given situation can be written in fraction, decimal and percentage form as,

Therefore, the fraction, decimal, and percentage form for the shaded squares will be , 0.81, and 81%, respectively.

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
