She forgot something in the question
To find out how much of the bottle of shampoo Sarah used on Fred, we need to first figure out how much of the bottle she had left after using 16/32 (or 1/2) on Sam.
1/2 - 16/32 = 16/32 - 16/32 = 0
This means she used up all of the shampoo on Sam, leaving none for Fred. Therefore, the answer is none of the above.
