Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Simeon drinks 64 fluid ounces of filtered water every day.  He used to drink this water in 8-ounce-servings.  But now, he drinks his water in 16-ounce servings.  How many fewer servings per day does it now take Simeon to drink his water than it used to?

### Response:
In 16-ounce servings, Simeon drinks 64 fluid ounces in 64/16=<<64/16=4>>4 servings.
In 8-ounce servings, Simeon drank 64 fluid ounces in 64/8=8 servings.
Thus, in 16-ounce servings, Simeon now drinks his water in 8-4=<<8-4=4>>4 fewer servings per day.
