There are 72 boys and 90 girls on the math team for the next math competition mr. johnson would like to arrange all of the students in equal rose with only girls or boys in each row what is the greatest number of students that can be in each row

18 stuents in each row

Step-by-step explanation:

72 = 2 * 2 * 2 * 3 * 3

90 = 2 * 3 * 3 * 5

The greatest common factor is 2 * 3 * 3 = 18

Answer is 18 in each row.

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
