The given numbers are in the ratio . Let the numbers be and , where is a real number.

The sum of the numbers is .

Solve for x,

.

Therefore, the numbers are,

or the numbers are .

X/y= 5/7

x+y=372

x=5/7y

5/7y+y=372

12/7y=372

y = 372(7/12)= 217

x= 155

x+y=372

x=5/7y

5/7y+y=372

12/7y=372

y = 372(7/12)= 217

x= 155
