Sarah used 1/9 of the bottle of shampoo on Fred.
To find out how much of the bottle of shampoo Sarah used on Fred, we need to calculate the amount of shampoo left after she used it on Sam.
Step 1: Start with 1 whole bottle of shampoo.
Step 2: Sarah used 1/6 of the bottle on Sam. To find out how much is left, we subtract 1/6 from 1.
1 - 1/6 = 5/6
Step 3: Now, Sarah uses 1/3 of what is left on Fred. To calculate this, we multiply the remaining amount (5/6) by 1/3.
(5/6) * (1/3) = 5/18
Therefore, Sarah used 5/18 of the bottle of shampoo on Fred.
To find the amount of shampoo Sarah used on Fred, we first need to calculate how much was left after she used 1/6 on Sam.
Let's start with the whole bottle of shampoo.
Step 1: Take the whole bottle as 1.
Next, Sarah uses 1/6 of the bottle on Sam. To find out how much shampoo is left:
Step 2: Subtract 1/6 from 1.
1 - 1/6 = 6/6 - 1/6 = 5/6.
So, after using 1/6 on Sam, Sarah has 5/6 of the bottle of shampoo left.
Now, she uses 1/3 of what was left on Fred. To find out how much shampoo she used on Fred:
Step 3: Multiply 5/6 by 1/3.
5/6 * 1/3 = 5/18.
Therefore, Sarah used 5/18 of the bottle of shampoo on Fred.
