A factory uses 1/8 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 3/4 of a barrel of raisins.
dimaraw [331]

Answer: 6

Step-by-step explanation:

From the question, we are informed that a factory uses 1/8 of a barrel of raisins in each batch of granola bars and that the factory used 3/4 of a barrel of raisins yesterday.

To calculate the number of batches of granola bars that the factory made yesterday, we divide 3/4 by 1/8. This will be:

= 3/4 ÷ 1/8

= 3/4 × 8/1

= 24/4

= 6

The company made 6 batches of granola bars
