The ratio of three numbers is 4 : 3 : 1. the sum of the numbers is 64. the greatest of these three numbers is

The greatest number is 32 .

Step-by-step explanation:

As given

The ratio of three numbers is 4 : 3 : 1.

The sum of the numbers is 64.

Let us assume that the x be the scalar multiple of the numbers .

First number = 4x

Second number = 3x

Third number = x

Than the equation becomes

4x + 3x + x =  64

8x = 64

x = 8

Thus

First number = 4x

                     = 4 × 8

                     = 32

Second numbers = 3x

                             = 3 × 8

                             = 24

Third number = x

                       = 8

Therefore the greatest number is 32 .

the one that has a slope of 1/2 and is positive.
