To determine which store has more DVDs, we need to compare the actual quantities of DVDs in each store, rather than just the ratio of DVDs to videos. The ratios provided only indicate the proportion of DVDs to videos in each store, not the actual number of DVDs.
Let's break it down step by step:
In the first store, the ratio of DVDs to videos is 7:5. This means that for every 7 DVDs, there are 5 videos. However, we don't know the actual quantity of DVDs or videos in this store.
Similarly, in the second store, the ratio of DVDs to videos is 4:3, which suggests that for every 4 DVDs, there are 3 videos. Again, we don't know the actual quantities.
Since we don't have any information regarding the actual number of DVDs in each store, we cannot determine which store has more DVDs solely based on the given ratios. To make a comparison, we would need to know either the total number of DVDs or the total number of videos in each store.
Therefore, without additional information, it is not possible to determine which store has more DVDs.
