Dan is solving 18 x 16. He used model to help work through each step. Which calculation did Dan make to get the highlighted partial product?

ANSWER
8 x 6
EXPLANATION
We have the area model that represents the product of the two numbers 18 * 16.
From the area model, we have 4 partial products:
10 x 10 = 100
10 x 6 = 60
8 x 10 = 80
8 x 6 = 48
Therefore, the partial product that represents 48 is 8 x 6.
