Answer:
The factory made 4 batches of cookies.
Step by step explanation:
To determine the number of batches of cookies the factory made, we need to find how many times 1/8 barrel fits into 1/2 barrel.
Given that 1/2 barrel was used yesterday and each batch requires 1/8 barrel of oatmeal, we can set up the following equation:
(1/8) * x = 1/2
To solve for x (the number of batches), we can multiply both sides of the equation by the reciprocal of 1/8, which is 8/1:
(1/8) * x * (8/1) = (1/2) * (8/1)
Simplifying the equation:
x = 4
Therefore, the factory made 4 batches of cookies.
