To solve this problem you must apply the proccedure shown below:

1. The halving and doubling is a multiplication strategy which is very useful to simplify products.

2. You have the following multiplication given in the problem above:


(28)(50)

3. Then, by applying this strategy, you have that the double of 50 is 100 and the half of 28 is 14. Therefore, when you multiply them, you obtain:


(14)(100)=1400

Therefore, the answer is:
(28)(50)=(14)(100)=1400.
