Answer 1

1.24 inches is the best answer

Answer 2

So, let's make these two values improper fractions so they're easier to work with.

So, to get the rate he grew in those months we have:

`\frac{(13)/(3) \text{inches}}{(7)/(2)\text{months}} =\frac{26\text{inches}}{21\text{months}}`

And to get the rate he grew in one month we have to divide both our numerator and our denominator by 21 to get:

`\frac{(26)/(21) \text{inches}}{\text{month}}\approx \frac{1.24\text{inches}}{\text{month}}` aka he grew 1.24 inches in a month.
