Answer 1

To find the product of 13 × 18 using partial products, we can break it down into smaller parts.

We can express 13 and 18 in terms of their place values:

• 13 = 10 + 3
• 18 = 10 + 8

Using these values, we can create a multiplication array and find the partial products:

1. Multiply 10 (from 13) and 10 (from 18) = 100
2. Multiply 10 (from 13) and 8 (from 18) = 80
3. Multiply 3 (from 13) and 10 (from 18) = 30
4. Multiply 3 (from 13) and 8 (from 18) = 24

Now we can list the partial products we found:

• 100 (10 × 10)
• 80 (10 × 8)
• 30 (3 × 10)
• 24 (3 × 8)

To find the total product of 13 × 18, Ani should add these partial products together:

100 + 80 + 30 + 24

Looking at the choices provided, the correct response is:

24 + 30 + 80 + 100
