let's try it one by one

Step-by-step explanation:

5605 ÷ 9 = 622.7777 [not right]

5615 ÷ 9 = 623.8888 [not right]

5625 ÷ 9 = 625 [right!]

5635 ÷ 9 = 626.11111111 [not right]

5645 ÷ 9 = 627.2222 [not right]

5655 ÷ 9 = 628.3333 [not right]

5665 ÷ 9 = 629.4444 [not right]

5675 ÷ 9 = 630.5555 [not right]

5685 ÷ 9 = 631.6666 [not right]

5695 ÷ 9 = 632.7777 [not right]
