Step-by-step explanation:
Okay, to find the ratio, add up all the numbers of DVDs.
You should end up with 36 DVDs.
The question states that you need to find the ratio between the action DVDs and the total amount of DVDs.
The amount of action DVDs is 12.
Now take 32 and 12, the ratio of the action DVDs and the total amount of DVDs to get your ratio.
The ratio is 12 out of 31, or 12:32
