The last one: numerator 12 and denominator 30.

Step-by-step explanation:

Since the total amount is 30, it would be the denominator, and he has only done 12 out of the 30, so 12 would be the numerator. The fraction would look like this: 12/30.

(hope this helps :P)

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a
