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.
Sarah used 16
of a bottle of shampoo on her dog Sam, and 13
of what was left on her dog Fred. How much of the bottle of shampoo did she use on Fred?
