Initially, Sarah used 1/6 of the shampoo bottle on her dog Sam, which means there were 5/6 of the shampoo left.
Then, she used 1/3 of what was left on her dog Fred. So, she used:
1/3 * 5/6 = 5/18
of the bottle of shampoo on Fred. Therefore, the answer is C) 5/18.
To find out how much of the bottle of shampoo Sarah used on Fred, we first need to calculate how much shampoo was left after using 1/6 on Sam.
If Sarah used 1/6 of the bottle of shampoo on Sam, it means that 5/6 of the shampoo is left.
Now, to find out how much shampoo Sarah used on Fred, we need to calculate 1/3 of the remaining 5/6.
To do this, we multiply 5/6 by 1/3:
(5/6) * (1/3) = (5/18)
Therefore, Sarah used 5/18 of the bottle of shampoo on Fred.
So, the correct answer is C) 5/18.
