Find the greatest common factor (GFC) for this pair of composite numbers. 10 and 15

Given:

The pair of composite numbers: 10 and 15

To find:

The greatest common factor (GFC) for the given pair of composite numbers.

Solution:

Two composite number are 10 and 15.

The factor forms of these two numbers are

It is clear that the common factor is 5 in both factor forms. So, the greatest common factor is

Therefore, the greatest common factor of 10 and 15 is 5.

answer: you have to send a photo of the question

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
