Answer: It will be made into 336 portions.
Explanation:
42 divided into 1/8
42 = 42/1
When dividing fractions, we follow a rule called "Keep, change, flip"
You keep the first fraction, change the symbol into multiplication, and flip the second fractions.
42/1 * 8/1 = 336/1
Therefore, there will be 336 portions from every batch.
