-7 is rational and integer

-3/7 is rational

0 is rational, integer, and whole

.5 is rational

squareroot of 7 is irrational

3.1 is rational

square root of 16 is rational, natural, whole, and integer

1. 1/9 since you take all the "a"s in the words which is 2/18
2.2/9 same thing as above
3.18/18 since there is no "O" it's a trick question
4.3/9
5.5/6 since you don't count 6
6.1/2 and 1/2 coins are always 1/2 unless you flip twice
7.5/13
8.1/2 because 1,3,5 odd 2,4,6 even 
Hope that helps
