Answer:
No, Winnie cannot download 19 podcasts that each take up 1 GB in memory.
Explanation:
Winnie's phone has 4 GB of memory left, and each podcast takes up 1 GB, so Winnie can only download 4 podcasts.
In order to calculate this, we can divide the total amount of memory left by the amount of memory each podcast takes up:


Therefore, Winnie can only download 4 podcasts.
Even if Winnie deleted all of the data on her phone, she would still not be able to download all 19 podcasts, because the podcasts would take up more memory than the total amount of memory on her phone.
In order to calculate this, we can multiply the number of podcasts by the amount of memory each podcast takes up:


Therefore, the podcasts would take up 19 GB of memory, which is more than the total amount of memory on Winnie's phone (4 GB).
