Answer 1

He grew about 1 1/5 inches in one month.

Answer 2

`1(5)/(21)\text{ inches}`

Explanation:

Given,

Growing of pedro in
`3(1)/(2)` months =
`4(1)/(3)` inches

`\because 3(1)/(2)=(7)/(2)`

And,

`4(1)/(3)=(13)/(3)`

So, the Growing of pedro in
`(7)/(2)` months =
`(13)/(3)` inches,

Thus, the growing of pedro in 1 months =
`(13)/(3)* (2)/(7)`

`=(26)/(21)`

`=1(5)/(21)\text{ inches}`
