Question

a. what is the product of 8 × 619? fill in the area mo the partial products.
600 + 10 + 9
8 ____ __
b. 8 × 619 = ______

Explanation:

Step1: Calculate partial products

First, find the product of 8 and 600: $8\times600 = 4800$.
Then, find the product of 8 and 10: $8\times10 = 80$.
Next, find the product of 8 and 9: $8\times9 = 72$.

Step2: Sum the partial products

Add the three partial products together: $4800 + 80 + 72$.
First, $4800 + 80 = 4880$. Then, $4880 + 72 = 4952$.

Answer:

a. The partial products are 4800, 80, and 72 (filling the boxes from left to right as 4800, 80, 72).
b. $8\times619 = \boldsymbol{4952}$
