X/y= 5/7

x+y=372

x=5/7y

5/7y+y=372


12/7y=372

y = 372(7/12)= 217


x= 155

The given numbers are in the ratio 5:7. Let the numbers be 5x and 7x, where x is a real number.

The sum of the numbers is 5x+7x=372.

Solve for x,

12x=372\\ x= \frac{372}{12}\\ x=31.

Therefore, the numbers are,

5*31,7*31 or the numbers are 155,217.
