Hi

The difference of the squares is of two numbers is 80% of the sum of their squares .

What will be the the ratio of the larger number to the smaller number  ?

 

     .2x^2 = 1.8y^2

      

       x/y = 3/1

 The difference of the squares of two numbers is 80% of the sum of their squares. 

What will be the the ratio of the larger number to the smaller number ?

:

x^2 - y^2 = .8(x^2 + y^2)

x^2 - y^2 = .8x^2 + .8y^2

x^2 - .8x^2 = .8y^2 + y^2

.2x^2 = 1.8y^2

multiply both sides by 5

x^2 = 9y^2

Find the square root of both sides

x = 3y

Ratio of two numbers: 3:1
