To determine how much of the bottle of shampoo Sarah used on Fred, we need to subtract the amount used on Sam from the initial amount of shampoo in the bottle.
The fraction used on Sam is 16/16, which can also be written as 1.
The remaining shampoo in the bottle can be calculated by subtracting the amount used on Sam (1) from the total amount in the bottle (1). Thus, the remaining amount is 1 - 1 = 0.
Since there is no shampoo left in the bottle, Sarah cannot use any on Fred. Therefore, the correct answer is 0.
Answer: D - 0
