I need help on this math problem.

1 - 3/4= 1/4

Step-by-step explanation:

The top rectangle equals to 1 which is the Minuend (larger number that is being subtracted from)  it is also highlighted in red. There is 3/4 highlighted in blue and is under the red rectangle (1). The diagram shows the difference of 1-3/4=1/4 because the 4/4 equals 1 and the last 1/4 is not highlighted so

1 - 3/4 = 1/4

an altitude of 15,000 feet

step-by-step explanation:

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
