Question

Choose the multiplication problem that correctly shows partial products.

A) A
B) B
C) C

Answer 1

B

Explanation:

82

5

--

5 x 2 = 0 (carry 1)

5 x 8 + 1 = 1 (carry 4 to bottom)

Answer 2

B) B

Explanation:

In this case, the first partial product will be 2 * 5 which is 10. The only option that shows this is option B, so this is our answer.

We can also check the answers as a whole,

2 * 5 = 10

80 * 5= 400

400 + 1 = 410

Again, only option B gives us this. This is means that option B is our answer.
