Answer 1

Table

Top right:
`5+194=199`

Middle right:
`217+13=230`

Bottom left:
`5+217=222`

Bottom middle:
`194+13=207`

Bottom right:
`222+207=429`

Question 1

`(207)/(429) \approx \boxed{0.4825}`

Question 2

`(13)/(429) \approx \boxed{0.0303}`

Question 3

`(194+217)/(429) \approx \boxed{0.9580}`
