Hi, you have to multiply 35 by each ratio to find the two numbers.  9 (35) and 13 (35).

First, you add 13 and 9 which is 22. Then we divide 770 by 22 resulting to 35. Finally, we multiply 35 to 13 and 9 arriving to 315 and 445 which are now the numbers. :)

Check:
445 + 315 = 770

315 : 445 (lowest term)
9 : 13
