Answer 1

24108 is your answer trust me i did this before

Answer 2

Answer:

861×28 = 24108        

Step-by-step explanation:

We have to use partial product strategy to solve this multiplication problem.

Partial product strategy is an easy way or technique that helps us to solve multi-digit multiplication by breaking down the complicated digits into smaller units

$861\times 28$

With the help of partial product strategy it can be written as:

$(800 + 60)\times (30-2) + 28$

We use the identity: $(a+b)(c-d) = ac - ad +bc -bd$

$(800 + 60)\times (30-2) + 28\\=24000 - 1600 +1800 - 120 + 28\\= 24108$
