Answer:
4 2/6 pounds left to stock
Step-by-step explanation:
1/2 is equivalent to 3/6 so subtracting the 1/6 of a pound that Sarah has already stocked you would get 2/6. Just remember the 4 full pounds as that does need to be added back. Another note is when subtracting it helps to set the fractions with a common denominator, in this case being 6.
