To find out how many raisins are in 12 bags, we first need to determine the number of raisins in one bag.
We know that:
\[ \text{Number of raisins in one bag} = \frac{\text{Total number of raisins}}{\text{Number of bags}} = \frac{680}{8} = 85 \]
Now that we know each bag contains 85 raisins, we can find the total number of raisins in 12 bags:
\[ \text{Total number of raisins in 12 bags} = \text{Number of raisins in one bag} \times \text{Number of bags} = 85 \times 12 \]
Calculating that:
\[ 85 \times 12 = 1020 \]
Thus, there are 1,020 raisins in 12 bags.
